Which statement correctly describes magnetic field lines?
A
Magnetic field lines never cross and always point from the south pole to the north pole outside the magnet.
B
Outside a magnet, magnetic field lines emerge from the north pole and enter the south pole, and the lines form continuous closed loops.
C
Magnetic field lines are straight, parallel lines everywhere around a bar magnet.
D
Magnetic field lines begin at isolated north magnetic charges and end at isolated south magnetic charges.
