PHY 102 Electromagnetic Induction 1 Objective Question

Question

What type of electric current is specifically generated by a rotating loop in a uniform magnetic field, as described in the 'Rotating Loop - The Electric Generator' section?
Options
A Direct Current (DC)
B Alternating Current (AC)
Correct Answer
C Pulsed Current (PC)
D Static Current (SC)
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 23 states: 'This is an AC (alternating current) generator.' The formula for EMF (BAω sin(ωt)) clearly shows a sinusoidal variation, characteristic of alternating current.

Hint

The EMF produced by a rotating loop is sinusoidal in nature.
