Magnetic field at the centre of a circular coil of radius R due to curent i flowing through it is B. The magnetic field at a point along the axis at distance R from the centre is :

Determine the magnetic induction at the centre of a circular coil of radius r carrying a current I with the help of the Biot-Savart law.

Obtain an expression for magnetic flux density B at the centre of a circular coil of radius R, having N turns and carrying a current I.

How will the magnetic field induction at the centre of a circular coil carrying current change, if the current through the coil is doubled and the radius of the coil is halved?
