Statement-1 The net magnetic flux through a spherical surface enclosing north pole of a bar magnet as zero

Statement-2 Magnetic field lines always form closed loops

Options

A. If both assertion and reason are true and reason is the correct explanation of assertion.
B. If both assertion and reason are true but reason is the correct explanation of assertion.
C. If assertion is true but reason is false
D. If both assertion and reason are false.

Answer

A

Explanation

Magnetic poles exist in paris. It is not possible to isolate a north pole or a south pole. Magnetic field lines start from the north pole and go to the south pole and return to the north pole. They form continuous closed loop unlike electric lines of force which do not as electric monopole, single charge does exist.
