electricity and magnatism

Magnet can be made of

• Copper

• Glass

• Iron

• Plastic

The area around the magnet in which its force appears is known as

• Electric current

• Magnetism

• Magnetic field

• Air

Some materials cannot be attracted to the magnet because they are

• Magnetic material

• Non magnetic material

• Located in the magnetic field

Magnet affect certain objects like ………..when they locate in its magnetic field

• Wood and steel

• Iron and copper

• Nickel and plastic

• Cobalt and steel

A piece of aluminum foil and plastic spoon will be attracted to the magnet

• True

• False

Material number ….. will be attract to the magnet

• 1 only

• 2 only

• (1) and (2)

• (3)and (4)

Mechanical energy is converted into….. energy in the generator

• Light

• Sound

• Electric

• Thermal

……….are used to spin the magnet in the generator to produce electricity

• Water and wind

• Light and sound

• Electricity and sound

• Sound and heat

Choose the correct arrangement

• d/b/a/f/c

• a/f/d/c/d

• c/d/b/a/f

• c/f/d/a/b

When the switch turned off ,it……….the circuit , so the electric current ………

• Open -will flow through

• Open-will not flow through

• Closed -will flow through

• Closed -will not flow through
