Best ResponseYou've already chosen the best response.2Coil a conducting wire very tightly around a cylindrical object as many times as possible and run a current through it. That is how electromagnets work. Do it with a strong enough current and enough coils and you can lift a car for example.

Best ResponseYou've already chosen the best response.2Ampere's Law is the formula you want to calculate the strength of the magnetic field you would make: \[B =μ_0 nI\]\[\text{where }I\text{ represents current}\]\[ n=\frac N\ell\text{ represents the number of turns per unit length}\]\[\text{and }\mu_0=4\pi\times10^{7}\text{ is the magnetic constant}\]

Best ResponseYou've already chosen the best response.0Just buy a Strong Neodymium Magnets from Radio Shack or the Internet. You didn't specify an electromagnetic force, so why not just use a permanent magnet?
