Question

Chapter 20, Problem 1QAP

To determine

If a current is suddenly set up in loop a, is there also a current in loop b, if yes, direction of the current and the direction of the force that is exerted on loop b by loop a.

Expert Solution & Answer

Answer to Problem 1QAP

There will be current in loop b in clockwise direction

Force exerted by the loop a on loop b will be downward in direction

Explanation of Solution

Given info:

Current is suddenly set up in loop a

Concept Explanation:

When a current start to flow on loop a, changing magnetic field is created to upward direction. According to the Lenz law due to this changing magnetic field a current is induced in loop b. This current is induced in a way that resulting magnetic field due to this current opposes the magnetic field produced by loop a. Therefore, the current that flows on loop b will be the opposite direction to the current flows on loop a. Currents flows in opposite directions producing a magnetic force downwards.

Conclusion:

There will be current in loop b in clockwise direction

Force exerted by the loop a on loop b will be downward in direction
