Question

a long solenoid has 20 turns per cm. calculate the magnetic induction at the interior point on the x is for a current of 200 ma​

Answer 1

Answer:

Explanation:

We can use the formula:

Fy = B vector . A vector

Magnetic flux = dot product of magnetic field and area vector.

Or e = -N d fy/dt ( by Faraday lenz law)

And,

I = Blv/ R

I hope it will help you
