I need help making an elctromagnet for school. Can I get some help?

You need something iron (like a nail) wrap the wire around to make an electromagnet. You could wrap the wood lengthways with some wire and then wrap another wire shortways around the assembly and hook to the battery but an iron core is much better. \n http://www.energyquest.ca.gov/projects/electromagnet.html\nBTW You do have most of the parts to make a simple radio receiver also.

Create an electromagnet by coiling the wire around the steel rod and attatching the wire to the power supply (put the ammeter in the circuit somewhere (in series). Use the retort stands to hold the weighing scales above the electromagnet. Place the 6 magnets in the weighing scale whilie the power supply is off. See what the weight of the magnets is. switch the power on and see whether there is any change in the weight. try repeating this a few times using different currents (measured on the ammeter). 100grams=approx 1Newton of force

1. mico-elcetric currents are responsible for an elt's magnetic props...\n\n2. electron motion or spin in atoms

OK I'm cheating - I put this answer up a little while ago.\n\nA quick and dirty idea for a physics project would be one based on electromagnetism. Without knowing what grade you're targeting, a simple one that has a fair amount of pizzazz is to build a gauss rifle. Checkout http://sci-toys.com/scitoys/scitoys/magnets/gauss.html\n\nThe sci-toys site has some other pretty cool stuff that you might find useful as well.\n\nFor a more advanced example, you can make a small rail gun that applies similar principles but can have a much larger kick. Just do a search on "rail gun experiment".\n\nEnjoy!!

Try this, maybe?\n\nhttp://mathforum.org/library/drmath/drmath.elem.html

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

This looks good.\nwww.zycon.com/Magnets/Bar_Magnets.html \n\nThat being said, I'm sure you can mail in your magnets from other countries if required.

Since you need simple and portable, how about starting with something that uses light and prisms to create the spectrum? \nFrom there, you could go to show how rainbows are created ( where the light must be, what the sequence of the rainbow spectrum is) or compare how light colors mix compared to how m=paint colors mix.  I don't know if that is appropriate for the 10 th grade.  But working with light and prisms is always fun.\nmagnetism is always fun, too.

Im doing my Physics exam next year, and ive made spider diagrams and flash cards for keywords. Also, try putting post-its around your room with useful formulas and keywords.\n\nYou could also make a card game, by matching keywords and meanings, in a (sort of) fun way.

Here's some links that might help you with this project:\n\nhttp://gtalumni.org/Publications/magazine/spr92/physics.html\nwww.whps.org/schools/sedgwick/dox/science/SixFlags.doc \nhttp://solomon.physics.sc.edu/~tedeschi/midway/sixflagsanalysis.html\nhttp://www.carnegiemuseums.org/cmag/bk_issue/2000/sepoct/feat4.html\n\n\nGood luck with your project!\n~Tia~

Most magnets are formed by moving electrons. Each moving electron creates a small magnetic field. If lots of electrons are moving along the same path, they create a bigger magnetic field. Because of this you can make a magnet by using electric current. If you wrap a coil of wire around a piece of iron (like a big nail) and then put electricity through it using a battery, you will create a magnetic field. This is what we call an "electromagnet." Remember, only use batteries if you try this, never use a wall outlet--this is much too dangerous!!

that's sweet here i think is a link for a patent. I was thinking on how to make something like that, accelerating itself but i failed :P another of my questions was proven wrong leading me to the conclusion it is impossible for magnets to be used in mine.\n\nhttp://www.inventhelp.com/contactform_patent.asp?id=106&wcw=overture&GCID=S17330x002&KEYWORD=patent+office&MATCHTYPE=search

Get two pieces of iron block. Turn a coil round one of them. Pass electric current through the one which has the coil turned round it. This will make the coiled piece of iron act like a magnet and will attract the other piece of iron. And you have made an electromagnet.

You can take a magnetizable substance and change the polarity with electric coil or by rubbing another magnet in the same direction against the substance.  This will allign the mollecules changing the polarity of the object.

use a collimator.or magnetic fields.
