Acurrent 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

The radius of the loop is

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

Where, I = current

N = number of turns

B = magnetic field

r = radius

Put the value into the formula

Hence, The radius of the loop is

in physics zero. in muscle fatigue could be high
