Question

Using RHR-1, show that the emfs in the sides of the generator loop in Figure \(23.23\) are in the same sense and thus add.

Short answer

It is shown that the emfs in the sides of the generator loop in the figureare in the same sense and thus add up.

Step-by-step solution

Definition of RHR-1

The right-hand rule-\(1\) is a popular mnemonic for remembering how axes in three-dimensional space are oriented. The fact that the three axes of three-dimensional space have two different orientations gives birth to the majority of the many left-hand and right-hand rules.

Explanation

To have the same current on both sides, the current on one side should go up and the current on the other should go down. Now, on the right-hand side of the loop, the magnetic field is from left to right, and the velocity is into the paper, therefore current is flowing downwards from RHR-l.

The magnetic field is now from left to right on the other side of the loop, the velocity is out of the paper, and the current is now upward.

As a result, the currents are similar and add up.
