a person spilled a box filled with small objects on the floor. Why should that person try using a magnet to pi

because they are made of steel

One word : Revenge.  I suggest using super glue.  super glue her locker shut, super glue her books together, glue her shoes to the floor, glue all the buttons on her calculator, put glue in her hair, put glue in her food, glu anything that needs to move to work.  I love super glue <3

Get a magnet and try it.\n\nRead the last sentence of the link below:

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!

electromagnetic or magnetic fields. It is easiest to research and to do the practical of. Just place the magnets and use iron filings to measure it

It looked like the hover boards worked with some sort of magnet on the bottom that probably conteracted with the earth's magnetic force. Since, water isn't magnetic, the hoverboard wouldn't work on water. Thats what I thought at least.

Depends, if the attraction force of the magnet is bigger then the force of friction of the disc with the oil combined with the force necessary to break the surface tension. The weight and size of the disk are also very important.

Something is out of place or there is a fragment of paper left in there somewhere.  One or more sensor is not happy.

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.

I bet you saw my question!\n\nI think that the reason we can't figure it out is because it is totally obvious, and everyone is looking for a less immediate and very complicated technology. I would imagine it is actually a very simple design.\n\nBut an even easier solution would be to try and find the box. Surely he would not have destroyed it!

you should put it in a anti-static bag first then put it into bubble wrap or a jiffy bag,then for saftey and transit put it in a box filled with polystyrene

The bottle was probably made of crystal metal and electromagnets are placed under it.

Bad idea because there is a higher probability that the board might create a short circuit and "fry" you processor, RAM, and other fragile hardware. It's always best to secure the board to the case chassis because it not only creates stability - it also ensures proper grounding.

Magnets can repel only magnetic substances or that are electrically charged. Further there are substances called diamagnetics substances that are weakly repelled by magnets. So if the dirt contains something magnetic or charged they may be repelled. However, water cannot be repelled by magnet.

piece of metal that is exposed to an electromagnetic field\n\n\nBasically the individual atoms of the material are polarized to begin with, but they're scrambled among each other. Putting them in a magnetic field just makes many of them align and have a higher degree of directional attraction.
