Answer 1

Explanation:

please follow me

Magnetic field lines represent continuous curves that originate at the north pole of a magnet and end at the south pole. ... Therefore, the magnetic field lines are continuous and form closed loops.

Answer 2

Explanation:

D). NONE OF THESE

REASON:- 90 FIELD LINES ARE CONTINUOUS CURVES. IT ORIGINATE FROM NORTH POLE AND TERMINATE ON SOUTH POLE. BUT INSIDE THE MAGNET IT MOVE FROM SOUTH POLE TO NORTH POLE FORMING A CLOSED LOOP. SO THERE IS NO ANY ORGANISATION OR TERMINATION POINT LIKE THE ELECTRIC FIELD.
