Magnetism Quiz

Let's get started with the Magnetism Quiz

Which of these would occur if two like poles of a pair of magnets were placed near each other?

Attraction

It depends on the size of the magnet

Nothing

Repulsion

Where is the magnetic force around a magnet the strongest?

Around both poles of the magnet

Around the middle of the magnet

Around the north pole of the magnet

Around the south pole of the magnet

Which of these is not a naturally occurring magnetic material?

Cobalt

Iron

Nickel

Copper

Where is the magnetic force around a magnet the weakest?

Around both poles of the magnet

Around the middle of the magnet

Around the north pole of the magnet

Around the south pole of the magnet

Which of the following correctly describes the direction of a magnetic field at any given point?

The direction is always towards the middle of the magnet

The direction is always from the north pole to the south pole

The direction is given by the direction of the force that would act on another south pole placed at that point

The direction is given by the direction of the force that would act on another north pole placed at that point

What happens when a current flows through a wire?

A magnetic field is produced around the wire

Nothing happens

The wire becomes negatively charged

The wire becomes positively charged

Which of the following is the correct definition of an electromagnet?

A magnet which needs to be plugged in and charged

A magnet which requires energy to work

A solenoid with an iron core

A solenoid with a copper core

Which of the following is the correct definition of a magnetic compass?

A device containing a magnetised needle that rotates on a pivot and points in the direction of the Earth’s magnetic field

A device containing a magnetised needle that rotates on a pivot and points in the opposite direction to the Earth’s magnetic field

A device containing a needle that rotates on a pivot and points in the direction of the Earth’s magnetic field

A device containing a needle that rotates on a pivot and points in the opposite direction to the Earth’s magnetic field

The magnetic field of a solenoid is similar to the magnetic field around which of the following objects?

Bar magnet

Compass

Horseshoe magnet

Ring magnet

10.

Which of the following correctly describes the difference between a permanent and an induced magnet?

An induced magnet is a magnet which produces its own magnetic field, whereas a permanent magnet is a material which becomes a magnet when placed in a magnetic field

A permanent magnet is a magnet which produces its own magnetic field, whereas an induced magnet is a material which becomes a magnet when placed in a magnetic field

A permanent magnet contains iron, whereas an induced magnet contains cobalt or nickel

A permanent magnet can be turned on or off, whereas an induced magnet is constantly on once magnetised
