Question

According to Faraday, what is produced by a changing magnetic field?

Answer 1

Answer:

c. Induced voltage.

Explanation:

Faraday's law says

$\varepsilon = N \dfrac{d \Phi_B}{dt},$

or in words,

"A changing magnetic flux induces an emf (potential difference) in a coil of wire "

This potential difference is induced, and therefore, we can also call it "induced voltage"; Hence, from the choices given, choice C stands correct.

P.S: Another tempting choice is d; however, it is incorrect since induced emf is NOT an electrostatic force.
