A piece of steel is only slightly magnetised. It is struck several times with a hammer. What effect will this have on the steel?
- Aparallel to a strong magnetic field: it becomes magnetised more strongly; at right-angles to a weak magnetic field: it becomes magnetised more strongly
- Bparallel to a strong magnetic field: it becomes magnetised more strongly; at right-angles to a weak magnetic field: it loses its magnetism
- Cparallel to a strong magnetic field: it loses its magnetism; at right-angles to a weak magnetic field: it becomes magnetised more strongly
- Dparallel to a strong magnetic field: it loses its magnetism; at right-angles to a weak magnetic field: it loses its magnetism
