alleryMagnetic field lines around a bar magnet
AStart from north and end at south pole, never closing on themselves
BForm continuous closed loops, passing through the body of the magnet
CAre straight lines parallel to the magnet's axis
DIntersect at the equatorial plane
Answer & Solution
Correct answer: B. Form continuous closed loops, passing through the body of the magnet
Unlike electric field lines (open, from + to −), magnetic field lines always form CLOSED loops because magnetic monopoles do not exist.
