Magnetic Fields due to Currents
 

Magnetic Fields due to Currents problem 7


In the space inside a larger coil, there is a smaller coil, which is positioned so that its axis is perpendicular to the axis of the larger coil. The length of the larger coil is 40 cm, and the number of turns of the wire is 200. The smaller coil has 60 turns, a cross-sectional area of , and a current of 2 A flows through it.

How much torque acts on the smaller coil after passing through the larger coil which has an electric current of 5 A flowing through it? What position is the torque trying to put the smaller coil into?
