Looking at a ciruclar coil, the current found to be flowing in anticlockwise diretion. Predict the direction of magnetic field produced at a point on the axis of the coil on the same side as the observer

The direction of magnetic field produced on passing electric current in a conductor is determined by

state the rule to determine the direction of a current induced in a coil due to its rotation in a magnetic field.

State Biot-Savert's law. Use this law to find the magnetic field at a point on the axis of a circular coil carrying current.

The plane of a circular coil is horizontal. It has 10 turns each of radius 8cm. A current of 2 A flows through it. The current appears to flow clockwise from a point above the coil. Find the magnitude and direction of magnetic field at the centre of the coil due to the current.

What is the effect of increasing the number of turns on magnetic field produced due to a circular coil?
