Question

A current-carrying conductor of length L is placed in a uniform magnetic field of field strength B. Derive the force experienced by the conductor. Draw a clear diagram of a gadget that uses this force to make a balance - that is, a device that uses a current-carrying conductor to support the weight of an object. If you had a conducting rod that was 1m long and placed in the earth's magnetic field. Assuming that the earth's magnetic field makes an angle of 90 degree with the rod, how much current would you have to send through the rod so that it could lift you off the ground?

Explanation / Answer

a) Fb = L(I x B) = IBLsin

b)

c)

Fb = IBLsin

mg = IBLsin

I = (mg)/(BLsin)
