Question

Magnetic field at a point on the axis of a circular coil carrying current

Answer 1

Answer

Magnetic field at a point on the axis of a circular coil carrying current can be determined by using the Right Hand Thumb Rule.

We get to know then that:

When current : Clockwise, Current inside the coil : goes perpendicularly inwards

When current : Anti-Clockwise, Current inside the coil : comes perpendicularly outwards

Answer 2

Answer:

A current carrying wire generates a magnetic field. According to Biot-Savart's law, the magnetic field at a point due to an element of a conductor carrying current is, Directly proportional to the strength of the current, i. ... Inversely proportional to the square of the distance r between the element and the point.
