Question

A load is suspended from lower end of a vertical spring. If current flows in the
spring, what will happen?​

Answer 1

Answer:

The Spring will be compressed and the body attached at the end of the spring will be lifted upwards.

Explanation:

When the current is passed through a vertically suspended spring, the direction of currents in two adjoining parallel turns of wire is the same. Hence a force of attraction will be acting there. Due to it, the spring is compressed and the body attached at the end of spring is lifted upwards. The similar observations are made if the direction of current is reversed.
