Question

Problem 20b

Answer 1

Given information

Two current-carrying wires are parallel to each other 

Now, we need to determine that can the lower wire be held in stable equilibrium due to the magnetic force of the upper wire.

Step-by-step explanation

Step 1.

Usually, the magnetic force is stronger than the gravitational force. Hence, in the case of a lower wire, it will not consist of magnetic force equal to gravitational force. Hence, the difference between the gravitational force and magnetic force can provide a balance that will help to achieve equilibrium.
