OK, so it's a little confusing to me, but apparently the magnetic pole close to the north pole is actually a south magnetic pole.  So for some strange reason, the north pole of a magnet bar will be attracted to the south magnetic pole which is located near the north pole.\n\nNorth poles on a magnet are very easily found.  When you bring a magnet up to a coil, and move the north pole back and forth, you will get a current flow in a particular direction (counter clockwise).  \n\nIf you wish you can create your own magnet.  This way you can decide which end is north, and see which end points north.  You need to pass current in a counter clockwise motion.  Use your right hand and make a thumbs up sign.  Your fingers are pointing in the direction of the current, and your thumb is pointed in the direction of the north field.\n\nBest way is to take a wire and wrap it around a bolt at least 10 times.  Current leaves a battery on the positive terminal and enters the battery on the negative terminal.  Make sure you keep track of the direction of current flow.  Then use the right hand rule I indicated above.  The thumb shows the direction of the north magnetic pole.  I wish I could draw you a diagram.

Think of a magnet as a bunch of tiny magnets all aligned in the same direction. That's what gives it it's north-south poles. A piece of iron has those same tiny magnets inside, but they are not lined up. They are jumbled in all different directions and therefore the iron does not act like a magnet. But put it next to a magnet, at either pole, and all the pieces will line up with the magnet's tiny parts. Basically becoming part of the magnet. If the piece of iron stays next to the magnet long enough, the iron will stay magnetized even when moved away. But it will slowly get weaker as all its little magnet "parts" lose their alignment.

"The definition of Earth's magnetic poles depends on what is being defined. The "magnetic north/south pole" is the measured location of the vertical field lines. This is different from the "Geomagnetic north/south pole", which is the location where the best fitting dipole model pierces the surface of the Earth. While magnetic poles are not necessarily 180 degrees opposite from one another, Geomagnetic poles are exactly 180 degrees opposite from one another.\n\nThe magnetic south pole in 1990 was at 64.9 deg S 138.9deg E\n\nThe geomagnetic south pole in 1990 was 79.2 deg S 180.9 deg E "*\n\nDistance between Magnetic South Pole and Geographic South Pole (1990):    1456.8868 Statute Miles **\n\nDistance between Geomagnetic South Pole and Geographic South Pole (1990):   745.7051 Statute Miles **

.  Gravity and magnetism are two very different kinds of forces.  Gravity is always attractive and is proportional to the masses of two objects and how close together they are.  Magnetism can be attractive (pulling objects together) or repulsive (pushing them apart).  Magnetism is due to electric fields, either in the atoms of certain materials or electric fields resulting from electric currents in a sizable quantity of material.\n.  The earth might be a large magnet, with a net magnetic orientation in its solid iron inner core making the core a magnet, but its magnetic field is due mostly due to electric currents in the molten iron outer core which are generated by interactions with other magnetic fields.  We know that the earth is not like a permanent magnet because its magnetic field reverses periodically, about every 100,000 to 200,000 years.\n.   There are four basic forces in physics: gravity, the electromagnetic force, the weak nuclear force and the strong nuclear force.  Gravity seems to be quite different from the other forces.  Quantum mechanics can explain the other three forces and demonstrate how, at very high particle energies, they could be a single force.  Gravity,so far, can not be united in theory with the other forces.

Try this. Iron when combined with other metal elements becomes non-magnetic, yet with varying of the same elements is quite attracted to the magnet.Name the divisions of the metals and explain why.

bring the magnets close to each other. If u feel any repulsion, that means u have tried joining opposite poles.\nWith this test u just come to know of the repulsive and attractive sides relative to a magnet. No qualitative nalysis of which is North pole and which is south cannot be done! But hey! If the bar magnet is painted red on one side, then that would be the north pole!

It would point towards the magnetic pole which is somewhat south of the geographical North Pole. The 2005 location of the magnetic north pole is 79.74°N and 71.78°W

In North pole of Earth there is South pole of Earth's magnet and in the South pole of Earth there is North pole of Earth's magnet.

yes, just take a conical mold, pour in some molten iron, and keep it in a magnetic field as it cools. north and sout poles WILL be opposite sides, but it could have a weird overall field.

The pole in the north direction of earth is the south magnetic pole of earth's magnet.\n\nThe position of magnetic pole is changing but not the pole itself. If the pole cahnges then the magnetic needle in the compass will deflect in the opposite direction.

Okay, you know the right hand rule. Good.\nFirst consider the effect of only the e-field: The e-field is pointing in the +x direction. Therefore, the force it exerts on the proton will also be in the +x direction.\nSecond, consider the effect of only the magnetic field: The magnetic field is pointing in the +y direction; therefore, the force it exerts on the proton will be in the -x direction (you use the rule you described to figure this part out). It so happens, that in the first scenario, the force exerted on the proton by the magnetic field exactly balances that exerted by the electric field. Therefore, the movement of the proton is unaffected.\n\nHowever, in the second case, the proton is accelerated through a potential difference of 2V. Therefore, it will be moving faster (think about it: a higher potential difference has greater "potential" to pull the proton.  Also, the equation F = qvB where q is the charge of the proton, v is its velocity, and B is the magnetic field strength, states that the faster the proton is moving, the greater will be the force exerted on it.  So, compared to the first case with only a 1V potential difference, the magnetic field here will exert a greater force on the proton. But, the force exerted by the electric field is unchanged. So, the net force on the proton will be in the -x direction.

When a current passes thru spring a magnetic feid is produced since the current pases in same direction in all coils of spring the magnetic feild will have same direction i all coils. So the N and S poles of adjascent magnets (coils) come near and thus attract. This causes the epring to reduce its length

The directional North pole of the earth is a magnetic south pole, this is because the north end of a compass points north, and opposites attract, therefore north is...south.\n\nMagnetic lines go from south to north i think, sorry havn't taken electricity/mag class in so long...\n\nanyways, if my thining is correct than it would point towards the directional south\n\ni'd choose "down"

When talking about a magnet large enough to be handled (and broken), it can be thought of as a collection of smaller magnets.  These smaller magnets are all aligned from north to south poles on each end.  If you got two 1" x 1/2" magnets, and put them end to end, N to S, they would make a magnet double the length of the original, and the ends would attract.  If you take the now 2" magnet apart, you have two magnets.  In practice, this is exactly what happened when you broke the magnet.  The pieces are still magnetic, with a north and south pole.  Therefore if you take the 2 pieces and put north to north or south to south, they will repel, and vice versa if north to south, they will attract.  No one yet has found just a south pole, or just a north pole, and that causes a stir in the scientific community.  You can keep crushing the magnet to bits and the tiny fragments will still have a north and south pole, and act like tiny little bar magnets.

Magnetic field has to do with the polarize charge of material, such as Iron.  \n\nIt is believed there is significant Iron near the center of the earth and yes rotation will cause the charges to align and thus create a magnetic field.  This is called the "Dynamo Theory".\n\nJUST BEING IRON DOES NOT MAKE THINGS MAGNETIC.\n\n"Previous theorists have assumed that the entire Core (or the Inner and/or Outer Core) rotates as a single flowing object within the Earth. If that were the case, then all of the charged (ionized) Iron material  would follow a relatively circular path around a single axis that we could call the Magnetic Axis. Basic Physics tells us that when electrical charges follow a closed (relatively) circular path (which is effectively a current), a magnetic field is always created as a result. The measurable evidence of this scenario would be a simple "dipole" magnetic field, with a single North Pole and a single South Pole, geographically exactly opposite each other on the surface of the Earth."\n\nSo if this theory where correct the Earth stopping it's rotation would in allow the magnetic field to fad.  But there are major problems with the theory.  For example it is known that the magnetic poles have flipped (Switched places) several time in Earths past.  Will if we have magnetic poles because of the earth's rotation to switch poles we'd need to reverse the cores rotation.  This would be an ungodly amount of energy.  There is nothing known that would do this once let alone a number of times.  And even if something could do it, we should have seen signs of the massive damage that would have resulted with these forces in play, like the Earth falling apart.   But in fact the poles shifting seems to be a pretty peaceful process on a planetary scale. \n\nAnd that is only one problem with the theory.  This is actually a very, very complex subject and there really is no way to know what effect the Earth stopping would have on the magnetic fields.  But I have attached a link to a very good article on the subject and it's pretty easy reading (Keeps the scientific jargon down and uses layman terms.)\n\nOthers are correct tough in what holds us to the Earth is gravity, not magnetics.  So it's the Mass (How big and dense it is) that keeps us here.  And rotation actually wants to make thing's fly away from it.  So we stay because the Earths gravity overcomes the acceleration.  So the acceleration of 1000mph is actually always enacting upon us, making us want to fly off the planet.  So stopping the Earth will not make us fly off as others have posted.\n\nThink of the spinning rids at the fairs and theme parks.  When you spin you are thrown away from the axis, the best example is the cylinder you go in and stand up against the wall.  When it spins your back is pushed against the wall, even as it turns so you are now spinning vertically like a tired, instead of horizontal like a top.  But when they stop the ride you don't go flying out.  That's because the wall holds you in and your move with the ride.  Well gravity acts like the wall and you move with the earth.\n\nYou would go flying of the earth if it continued to rotate and the gravity field somehow disappeared.

If a bar magnet breaks into two, then there will be two magnets, each with a N and a S pole.
