Question

Find the intensity of magnetic field at the centre of a
uniform circular current carrying loop having radius
10 cm when a current of 100 A is flowing through it.​



who is genius tell me answer ​

Answer 1

Given ,

Radius (r) = 10 cm or 0.1 cm

Current (I) = 100 amp

We know that , magnetic field at the centre of a circular loop is given by

$\boxed{ \tt{B = \frac{ u_{o}I }{2r} }}$

Thus ,

$: \mapsto \tt B = \frac{4\pi \times {(10)}^{ - 7} \times 100}{2 \times 0.1}$

$: \mapsto \tt B = 2\pi \times {(10)}^{ - 4}$

$: \mapsto \tt B = 6.28 \times {(10)}^{ - 4} \: \: T$

The intensity of magnetic field at the centre of circular current carrying loop is 6.28 × 10^(-4) T
