Question
A square loop of wire with a small resistance is moved with constant speed from a field free region into a region of uniform B field (B is constant in time) and then back into a field free region to the right. The self inductance of the loop is negligible. When entering the field the coil experiences a magnetic force to the right. Upon leaving the field, a clockwise current flows in the loop. When leaving the field the coil experiences a magnetic force to the right. Upon entering the field, a clockwise current flows in the loop.Explanation / Answer
a)true
here,
coil is entering into the field ,
the direction of the force is towrds right
b) true,
the indued current flows in a clockwise direction
c) false,
the direction of the magnetic force is towards left
d) false,
the indued current flows in a anticlockwise direction
