Magnetic Induction and Demagnetization

Things to remember

• Magnetic induction is the process by which substances like iron are magnetised by the magnetic field.
• Demagnetization means decreasing magnetic property or losing it completely.
• There are various ways to demagnetize a magnet. for instance, Dropping regularly from the table or height, Rubbing against diamagnetic substances etc.
• In the magnet, each and every small part of the magnet is directed in the north and the south directions.
