A current I ampere flows along an infinitely long straight thin walled tube, then the magnetic induction at any point inside the tube is .

A

Zero

B

Infinity

C

`(mu_0I)/(2pi r)`

D

`(mu_0I)/(2)`

Text Solution

Verified by Experts

The correct Answer is:
A
The resultant magnetic induction at any point inside tube is zero because magnetic induction due to two curved surface are equal in magnitude and opposite in diretion.
