Question

A solenoid is 2.7 m long, has a radius 0.85 cm and has 600 turns. It carries a current i of 2.5 A. The magnitude of the magnetic field B inside the solenoid and far from the either end is​

Answer 1

Explanation:

ANSWER

Here,

I=4A

l=0.6m,

r=0.02m ∵

r

l

= 30 i.e. l >> r

n=

0.6

600

=1000 turns/m,

Hence, we can use long solenoid formula, then

∴ B=μ
