Question

When a current starts to flow in a stationary conductor placed in a time-varying magnetic field, what is the nature of the force acting on the stationary electrons that causes this current?
Options
A It is a Lorentz force (q<b>v</b>xB) due to the electron's motion.
B It is an electrostatic force (qEe) due to stationary charges.
C It is a force (F=qE) due to an induced electric field (E).
Correct Answer
D It is a gravitational force.
Correct Answer

Option C is the correct answer.

Detailed Explanation

Page 27 clarifies: 'It is not F = qvxB, because the charges started stationary. Instead it must be the force F=qE due to an induced electric field E.'

Hint

The electrons are initially stationary, which rules out velocity-dependent forces.
