In a current carrying long solenoid, the field produced does not depend upon

A

number of turns per unit length

B

current flowing

C

radius of solenoid

D

all of the above

Text Solution

Verified by Experts

The correct Answer is:
C
As `B_(0)=mu_(0)ni`, therefore `B_(0)` does not depend upon radius (r) of the solenoid.
