According to Maxwell's hypothesis, a changing electrio field gives rise to

A

An `e.m.f`

B

Electric current

C

Magnetic field

D

Pressure radiant

Text Solution

Verified by Experts

The correct Answer is:
C
According to the Maxwell's `EM` theory, the `EM` waves propagation contains electric and magnetic field vibration in mutually perpendicular direction. Thus the changing of electric field five rise to magnetic field.
