Question

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

Select one:
a. Mirage
b. Convex
c. Induced voltage
d. Electrostatic force
e. Diffraction
f. Magnetic field
g. Dispersion
h. Electron clouds
i. Concave
j. Interference
k. Heisenberg's uncertainty principle

Answer 1

c. Induced voltage.

Step-by-step explanation:

Faraday's law says

`\varepsilon = N (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.
