Question

a 90 cm long solenoid has six layers of windings of 450 turns.if the diametre os solenoid is 2.2cm and current carried is 6A.Calculate the magnitude of magnetic field inside the solenoid near the centre​

Answer 1

Answer:

For six layers of windings the total number of turns =6×450=2700

Now number of turns per unit length n=

l

N

=

90×10

−2

2700

=3000

Then the field inside the solenoid near the centre

B=μ

0

nI=4π×10

−7

×3000×6=72πG

I hope this will help you... ❤️
