Solution
Methods that can be used to demagnetize a magnet.
- By hammering it -Permanent magnets can lose their magnetism if they are dropped or hammered.
- By burning it- If heated above a point a magnet will lose its magnetism.
- By applying a strong magnetic field - a flow of ac current disturb the alignment and arrangement of molecules of magnet, thereby cause the lose it's magnetism.
