Question:

A body is suspended from the lower end of a vertical spring. What shall be the effect on the position of the body when a current is sent through the spring?

Electric current:

In metals, there are some free electrons. When these free electrons flow through the metal for a specified time, then it is said that current is flowing. The direction of the current flow is in the opposite direction to the direction of electron flow.

Answer and Explanation:


When current is passed through the vertically suspended spring, then it can be clearly observed that the direction of current in two adjacent turns will be the same. This action leads to the formation of an attraction force in the turns of the spring.


Due to this attraction force, the turns of the spring come nearer to each other. This is how the spring is compressed, and hence the mass is lifted upward.
