i'm sure some of you are familiar with a gauss rifle. I'm doing an experiment using the magnets and marbles. does this at all relate to the gauss rifle guns.thanks

an old 'newbie' with first post. excuse my physics knowledge it has been a long time since college. >>>QUESTION below<<< Magnets repel (each other). If repelling 'each other' through a plane (ex. piece of glass) and water is allowed to flow over the plane. WHAT will happen to the water when...

Hi, Is it possible for two objects of nearly the exact same size, mass, and magnetic field strength to form something analogous to a curved space orbit in a relatively flat space by balancing inertia with magnetism? In other words, can two mutually magnetic objects orbit around a common center...

How do I figure out how much electricity would be generated by dropping a magnet down a coil of wire? What are the specific variables that would determine this? Is the number of coils more importants than the thickness of the wire and If it does generate electricity what's the best way to store...

Hey everyone, got a quickie for u. I'm not sure if there is a proper answer for this question, but could ppl give me brief theories to why superconductors repel magnets no matter what polarity they are. thanks for any input!

Check this site address out: http://scitoys/scitoys/scitoys/magnets/gauss.html It is a neat little science project site, and I found this project the most interesting (except for the non-elecricity requiring radio) on their site. How it tells you it works(shortened): You take a ruler and...

ok, I'm on my cell so forgive the spelling :) This question will be in stages so no one posts all the answers at once and nobody else gets to have fun... First Thing: let's explain How electricity is generated when sliding it through coils of wire. The equations would be very nice also, if...

DO NOT TRY THIS EXCEPT ON A JUNK TV OR MONITOR If you hold a strong permanent magnet up to a T.V. screen while it is on, the magnetic field does some really intriguing warping of the image. When you take the magnet away the image goes back to normal except that the color is now patchy and in-...

I am building a little experiment to demonstrate the impact of metal objects. It consists of the following two configurations: Magnets used are grade N38 NdFeB rare Earth magnets. ##RM## - Cylindrical magnet that is 1 1/2" long x 1/2" diameter laid lengthwise CM - 1/2" cube magnet B -...

My physics teacher gave the class a brief explanation of a permanent magnet. If I understood him correctly he basically said the special condition with a permanent magnet is that all the electrons are circling uniformly (in same direction). The poles of the magnet are based on the direction the...

A physics experiment with magnets and a vote pole-results This is an experiment with magnets in motion. The question is that if one magnet is spinning along a circular plane such that the north end arrives at a point on the circle just as often as the south end, then what will happen if...
