The document discusses the properties of magnetic and non-magnetic materials. It lists various objects and whether they are attracted to magnets. Magnets are made of iron, nickel, cobalt, or steel. Magnetic materials include cobalt knives, nickel coins, and iron nails. Non-magnetic materials include aluminum cans, copper coins, glass cups, wood, and plastic. The document also covers magnetic poles, how poles interact, magnetic fields, and electromagnets.

22. Conclusion

23. Magnetic Field
Magnetic Field is
the area of
magnetic force
around the
magnet

24. Electromagnet
By coiling the wire, magnetic field becomes
stronger

25. Electromagnet
Magnetic field becomes even stronger by
placing an iron bar in the center of the coil.
The electric
current changes
the iron nail to a
magnet.
