Physics Quiz Electromagnetism GCSE

Name two ways which you can make the electromagnet stronger.

What is the process called when a magnet moves into a coil of wire?

• Electromagnetic deduction

• Mr Davies effect

• Electromagnetic induction

• Magnetic friction

How would you increase the induced voltage in this circuit? (Could be more than one answer)

• Move the magnet faster

• Move the magnet slower through the coil

• Turn the magnet to the opposite direction

• More turns to the coil

• Stronger Magnet

Choose what the forefinger represents in Flemings left hand law.

• Field (South to North)

• Force

• Field (North to South)

What do field line patterns show?

• The direction of the magnetic field

• The direction and shape of the magnetic field

• The shape of the magnetic field

• None of the above

What advantage does an electromagnet have over a magnet?

• Stronger

• You can turn it off and on

• It attracts chocolate

What causes the motor effect?

• A current carrying wire exerting a force on an electromagnet

• A current carrying wire exerting a force on a temporary magnet

• A current carrying wire exerting a force on a permanent magnet

What do speakers contain?

• Magnet

• Magnet and electromagnet

• Electromagnet

Looking at this diagram of a transformer, describe the movement of electricity through the national grid.

Why is electrical power transmitted at high voltages in the national grid?

• Travels faster through the wires

• Lower current which means less heat loss

• Higher voltages doesn't electrocute people
