Magnetic Effects Of Current Question 68
Question: In a current carrying long solenoid, the field produced does not depend upon [MP PET 1999]
Options:
A) Number of turns per unit length
B) Current flowing through a conductor
C) Radius of the solenoid
D) All of the above three items
Show Answer
Answer:
Correct Answer: C
Solution:
Here $ B={\mu_{0}}ni $ where n is number of turns per unit length $ \tau =NBiA=100\times 0.5\times 1\times 400\times {{10}^{-4}}=2\ N-m $
