Magnetism is due to the magnetic fields around magnets. The fields can be investigated by looking at the effects of the forces they exert on other magnets and magnetic materials.
How many poles does a bar magnet have?
Which combination of magnetic poles will repel each other?
North and north
North and south
South and north
What will increase the strength of the magnetic field around a current?
Increasing the current
Moving further from the current
Switching the current off
What happens to an induced magnet when it leaves the magnetic field?
The magnetic poles swap places
The magnetism is lost
Its magnetism passes to the nearest magnetic material
An electric current flows through a wire. What happens to the magnetic field strength when the wire is shaped into a solenoid?
It stays the same
Where is a magnetic field strongest?
In the middle of each field line
Where the arrow is marked on each field line
Where the field lines are closest together
In which direction are the arrows on a magnetic field line?
From south pole to north pole
From north pole to south pole
In the direction a south pole would feel the magnetic force
What do a bar magnet and a solenoid have in common?
They are both permanent magnets
Their magnetic fields have a similar shape
They are both types of electromagnet
What force does a 10 cm wire carrying a current of 1 A experience when exposed to a 0.5 T magnetic field? - Higher
What does your thumb represent in Fleming's Left Hand rule? - Higher
