Question

A 150-turn coil has a current of 12 A. The radius of the coil is 0.050m and its length is 0.18 m. Magnetic flow through the circular area in the centre of the coil

Answer 1

I have solved your problem which is shown below:

Given that

N = number of turns = 150

I = Current = 12 A

radius = 0.05m

Length = 0.18 m

Using formula

n = Number of turns Per unit length= N/L

Substituting we get

So Magnetic flux inside this coil is

A = Area of the coil

Where r is the radius of the coil

We get

So Total Flux will be

Which is desired result
