Assertion: A direct current flows through a mettali rod, produce magnetic field only outside the rod.
Reason: There is no flow of charge carriers inside the rod.

A

Both A and R are true and R is the correct explanation of A

B

Both A and R are true but R is NOT the correct explanation of A

C

A is true but R is false

D

A is false and R is true

Text Solution

Verified by Experts

The correct Answer is:
C
Charge carries flows through whole cross-section. So, the field exists both inside and outside. So, the assertion is true and the reason is false.
