A freely suspended magnet always rests in the north-south direction. This helps in identifying the directions in new places. 3. Iron nail kept near magnet act as magnet due to magnetic induction. 4. Magnetic levitation helps to run electro-magnetic trains. 5. The attraction property of magnets helps in the separation of magnetic materials from their mixtures. 6. Electrical cranes are used to lift the huge weight of magnetic materials using this attraction property. 7. Magnets are useful in various equipment such as motors, speakers, etc.
