Magnetic field produced at the centre of circular coil having radius 0.1 m and 2 turns is _____ if `1/(4pi)A` current passes through it.

Text Solution

Verified by Experts

The correct Answer is:
(a) `B=1.41xx10^(-5)T`, with direction perpendicularly outward from the plane of figure
(b) `B=1.41xx10^(-5)T` with direction perpendicularly inward into the plane of figure.
Conclusion : Thus, these two fields are equal in magnitude and opposite in direction.
