Magnetic Poles and Fields

Cards (13)

What are the two types of magnetic pole?
North pole and South pole
What is a pole?
The place where the magnetic force is strongest
Describe the attraction of a north and south pole of two different magnets (Opposite poles)
The north pole will attract the south pole
Describe the attraction between a north pole and a north pole of two different magnets (Like poles)
The north pole will repel the north pole
Define the term magnetic field
The region around a field where a force acts on a magnet (Or magnetic material)
What is permanent magnet?
A magnet that creates its own magnetic fields
What is an induced magnet?
A magnet that only becomes a magnet when placed in a magnetic field
Describe the direction of magnetic field lines
From North to South
What do magnetic field lines show?
The direction of the force that would act on a north pole placed at that point
What does the magnetic flux density indicate?
The strength of the magnetic field
A magnet has a high flux density, what does this indicate about the magnet?
The magnet has a strong magnetic field
What happens when an induced magnetic pole is removed from a magnetic field?
It loses its magnetism quickly
A magnet's magnetic field lines are closer together. Does the magnet have a high low flux density?
High
