A steel bar is slightly magnetised. It is struck many times with a hammer.
What effect will this have on the magnetism of the steel bar?
Parallel to a strong magnetic field: It loses its magnetism. Perpendicular to any magnetic field: It becomes magnetised more strongly.
Parallel to a strong magnetic field: It becomes magnetised more strongly. Perpendicular to any magnetic field: It loses its magnetism.
