• Televisions

• Computers

What is the primary characteristic of a magnet?

• It can only be found in electronic devices.

• It repels all metals.

• It only works in the presence of electricity.

• It attracts iron and produces an external magnetic field.

What happens when opposite poles of two magnets are brought close to each other?

• They repel each other.

• They attract each other.

• They neutralize each other.

• They have no effect on each other.

How does a compass work?

• It uses a GPS signal to find direction.

• It aligns itself with the Earth's magnetic field.

• It uses a battery to point north.

• It relies on the position of the sun.

What mineral found in homing pigeons helps them navigate?

• Iron

• Copper

• Magnetite

• Nickel

What is the relationship between magnetism and electricity?

• Electricity destroys magnetic fields.

• They are completely unrelated.

• Electricity can generate a magnetic field.

• Magnetism can only exist without electricity.

What is the process called when a magnet generates an electric current in a wire?

• Electric conduction

• Magnetic resonance

• Magnetic reflection

• Electromagnetic induction

What is the primary function of the magnets in the drop car of a fairground ride?

• To generate electricity for the ride.

• To attract the car to the ground.

• To make the ride faster.

• To create a magnetic field that interacts with copper fins.

What is the effect of the opposing magnetic fields in the eddy current braking system?

• They have no effect on the car.

• They speed up the car.

• They bring the car to a halt.

• They make the car spin.
