PHY 102 Electromagnetic Induction 1 Objective Question

Question

The rotating loop described in the document, when placed in a uniform magnetic field and rotated with an angular frequency ω, functions as a generator that primarily produces what type of electrical output?
Options
A Direct Current (DC)
B Alternating Current (AC)
Correct Answer
C Pulsed DC
D Constant voltage with varying current
Correct Answer

Option B is the correct answer.

Detailed Explanation

Slide 23 explicitly states: 'This is an AC (alternating current) generator.' The EMF is given by E = BAω sin(ωt), which is a sinusoidal, time-varying, and alternating output.

Hint

Look at the functional form of the induced EMF for a rotating loop.
