Q. The method of magnetisation is:
✅ Correct Answer: (A)
Hammering a magnet
Explanation: Hammering a rod will either allow it to become slightly magnetic if laid along a magnetic field (i.e.North - South) or demagnetise it if laid across the field lines (i.e. East-West). A current passing through a coil will produce a magnetic field.
