alleryThe magnetic field lines of a bar magnet form:
AStraight lines
BBroken arcs
CClosed loops
DOpen curves
Answer & Solution
Correct answer: C. Closed loops
1. The field lines run out of the north pole and back into the south.
2. Inside the magnet they continue, so the paths close on themselves.
3. This is unlike the electric dipole, whose lines do not close.
