2. Electricity
•is the set of physical phenomena
associated with the presence and
motion of matter that has a
property of electric charge.

3. Magnet
•is a material or object that produces a
magnetic field. This magnetic field is
invisible but is responsible for the most
notable property of a magnet: a force that
pulls on other ferromagnetic materials, such
as iron, and attracts or repels other
magnets.

4. Properties of
Magnet

5. 1.Magnets have the ability to attract
materials that are magnetic in nature.
2.Like poles repel and unlike poles attract
3.When allowed to hang freely, magnets
have always align in one particular
direction.
4.Magnetic poles always occur in pairs.
