Question

Calculate the magnetic field at a point on the centre of the circular conductor of radius 2m with current 8a.

Answer 1

B=u2I/R
=4π×10^-7×2×4

Answer 2

Answer:

Magnetic field at a centre point of circular conductor is 2 Tesla.

Explanation:

Given in the problem is a circular conductor conductor of Radius 2m in which current flow is of 8A.

Magnetic field is produced in and around a conductor when current flows through it.

The Magnetic field (B)  in the centre of the circular conductor can be calculated by,

$B=\frac{I}{2r}=\frac{8}{2\times 2} =2\ Tesla$

Magnitude of magnetic field on the centre of the circular conductor is

2 Tesla.
