The net magnetic flux through any closed surface, kept in a magnetic field is

Assertion : The magnetic flux through a closed surface containing a bar magnet is zero. Reason : Gauss's law applies in the case of electric flux only.

Asseration: Magnetic flux linked to closed surface is zero. Reason: Direction of induced current due to change of magnetic flux is given by faraday's law.

Assertion (A): Two bar magnets attract when they are brought near to each other with the same pole. Reason (R): Unlike poles will attract each other.

If the net electric field flux passing through a closed surface is zero, then the electric field at the surface will be

Assertion (A): Whenever the magnetic flux linked with a closed coil changes there will be an induced emf as well as an induced current. Reason (R ) : Accroding to Faraday, the induced emf is inversely proportional to the rate of change of magnetic flux linked with a coil.

Assertion (A): The magnetic field configuration with 3 poles is not possible. Reason (R): No torque acts on a bar magnet itself due to its own field.
