A coil carrying current behaves as a/an

State Biot-Savart's law, giving the mathematical expression for it. Use this law to derive the expression for the magnetic field due to a circular coil carrying current at a point along its axis. How does a circular loop carrying current behave as a magnet?

A flat circular coil, carrying a current, has a magnetic moment mu

The magnetic induction at the center of a circular coil carrying current is

The magnetic moment of a circular coil carrying current is

The front face of a circular wire carrying current behaves like a north pole. The direction of current in this face of the circular wire is :

The field at the centre of a long circular coil carrying current will be parallel straight lines

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?
