PHY 102 Electromagnetic Induction 1 Objective Question

Question

In the context of 'Induced Electric Fields', why is the force on a stationary conductor experiencing a current not explained by the Lorentz force F = qvxB?
Options
A Because the magnetic field is too weak.
B Because the charges started stationary (v=0).
Correct Answer
C Because the conductor is non-magnetic.
D Because the current is direct current, not alternating.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Page 27 clarifies: 'It is not F = qvxB, because the charges started stationary.' If v=0, then qvxB = 0, so another force must be at play.

Hint

Recall the definition of the Lorentz force and the condition for it to act on a charge.
