Question

Two identical coils A and B of 500 turns each has on parallel planes such that 70% of flux produced by one coil links with the other. A current of 6A flowing in coil A produces a flux of 0.06m Wb in it. If the current in coil A changes from 10A to -10A in .30s, calculate (a) the mutual inductance and (b) the e.m.f induced in coil B.

Answer 1

When the knee is hit with a rubber hammer, the leg kicks forward, and then returns to the original position. This is an example of a spinal reflex arc. The sensation of the hammer travels to the, where it activates motor neurons that cause the leg to move. This reflex is part of the

nervous system.
