Question

A current of 02kA is traveling through a circularly looped wire. The wire makes 35 turns around an induced magnetic field of 8 9nt, each loop which is of equal size, What is the radius of one of these loops of

Answer 1

The radius of the loop is
`4.94*10^(5)\ m`

Step-by-step explanation:

Given that,

Current = 0.2kA = 200 A

Number of turns = 35

Magnetic field = 8.9 nT

We need to calculate the radius of one loop

Using formula of magnetic field

`B=(N\mu_(0)I)/(2r)`

`r=(N\mu_(0)I)/(2B)`

Where, I = current

N = number of turns

B = magnetic field

r = radius

Put the value into the formula

`r=(35*4\pi*10^(-7)*200)/(2*8.9*10^(-9))`

`r =494183.11\ m`

`r=4.94*10^(5)\ m`

Hence, The radius of the loop is
`4.94*10^(5)\ m`
