PHY 102 Electromagnetic Induction 1 Objective Question
Take CBT

Question

Does an induced electric field (E) exist in a region of space if a time-varying magnetic field is present, but no conductor is physically located there?
Options
A No, an induced electric field requires a conducting material to manifest.
B Yes, the induced electric field exists independently of the presence of a conductor.
Correct Answer
C Only if the time-varying magnetic field is exceptionally strong.
D Only if the space is a vacuum, not if it contains any gas.
Correct Answer

Option B is the correct answer.

Detailed Explanation

Slide 31 asks, 'Now suppose there is no conductor: Is there still an electric field?' and answers, 'YES! The field does not depend on the presence of the conductor.'

Hint

Think about whether a field is a property of space or a reaction of matter.
