Write Vio-Severt's law and with the help of this law, what is the reason for the current flowing in a circular coil?

Write the characteristics of magnetic field lines. Draw the magnetic field lines due to a current flowing in a circular coil.

The magnetic field induction at the centre of a current - carrying circular coil (coil 1) and a closed coil (coil 2), shaped as a quarter of a disc is found to be equal in magnitude. If both the coils have equal area, then find the ratio of the currents flowing in coil 2 and coil 1.

What are the basis of Kirchhoff's current law and voltage law ?

A constant current of 3.0 A flows counterclockwise in the circular coil in the following figure. What is the direction of the induced current in the coil on the right?

A circular coil 'A' has a radius R and the current flowing through it is I.Another circular coil 'B' has a radius 2R and if 21is the current flowing through it then the magnetic fields at the centre of the circular coil are in the ratio of
