Obtain an expression for magnetic induction at the centre of current carrying circular coil.

Derive an expression for the magnetic induction at the centre of a current carrying circular coil using Biot-Savart law.

Write the expression for magnetic field at the centre of a current carrying circular coil.

The ratio of magnetic field at the centre of a current carrying circular coil to its magnetic moment is 'r'. If the current and the radius both are doubled. The new ratio will become
