An electric field `(vec E)` and a magnetic field `(vec B)`exist in a region . The fields are not perpendicular to each other.

A

Electromagnetic wave must be passing through the given region

B

Electromagnetic wave may be passing through the given region

C

Electromagnetic wave may be passing through the given region

D

Given situation is not possible

Text Solution

Verified by Experts

The correct Answer is:
C

Suppose some electromagnetic wave is passing through a region then corresponding electric and magnetic fields will be mutually perpendicular but think that some additional source of electric or magnetic field is also present in that region then net electric and magnetic field will not remain perpendicular to each other.
