Poles of a magnet |
|
What are the poles of a magnet? Describe two experiments that can be used to identify the magnetic field pattern of a permanent magnet.
Describe what would happen if two North seeking Magnetic Poles were placed near each other, two South seeking Poles or one of each.
Which part of a permanent magnet is the strongest?
Investigate and draw the shape of the magnetic field pattern around a permanent magnet.
Investigate the effect that two magnets have on each other in different orientations. |
|
|
|
The region around a magnet where a force acts on another magnet or on a magnetic material (iron, steel, cobalt and nickel) is called the magnetic field. |
|
What is the magnetic field? |
|
|
|
The force between a magnet and a magnetic material is always one of attraction. |
|
What force is always between a magnet and a magnetic material? |
|
|
|
When two magnets are brought close together they exert a force on each other. |
|
What happens when two magnets are brought close together? |
|
|
|
The strength of the magnetic field depends on the distance from the magnet. The field is strongest at the poles of the magnet. |
|
What does the strength of the magnetic field depend on and where is it the strongest? |
|
|
|
Two like poles repel each other. |
|
What happens when two like poles are brought together? |
|
|
|
The direction of the magnetic field at any point is given by the direction of the force that would act on another north pole placed at that point. |
|
What affects the direction of the magnetic field? |
|
|
|
Two unlike poles attract each other. |
|
What happens when two unlike poles are brought together? |
|
|
|
The direction of a magnetic field line is from the north
(seeking) pole of a magnet to the south(seeking) pole of the magnet. |
|
What direction does the magnetic field line go in? |
|
|
|
Attraction and repulsion between two magnetic poles are examples of non-contact force. |
|
What type of force are attraction and repulsion between magnetic poles examples of? |
|
|
|
A magnetic compass contains a small bar magnet. The Earth has a magnetic field. The compass needle points in the direction of the Earth's magnetic field. |
|
What causes a magnetic compass to follow the direction of the Earth's magnetic field? |
|
|
|
A permanent magnet produces its own magnetic field. |
|
What is a permanent magnet? |
|
|
|
Students should be able to describe how to plot the magnetic field pattern of a magnet using a compass. |
|
How can a plotting compass be used to plot the magnetic field pattern of a magnet? |
|
|
|
An induced magnet is a material that becomes a magnet when it is placed in a magnetic field. |
|
What is an induced magnet? |
|
|
|
Students should be able to draw the magnetic field pattern of a bar magnet showing how strength and direction change from one point to another. |
|
|
|
|
|
Induced magnetism always causes a force of
attraction. |
|
What force does induced magnetism always cause? |
|
|
|
Students should be able to explain how the behaviour of a magnetic compass is related to evidence that the core of the Earth must be magnetic. |
|
Why does a compass point North? |
|
|
|
When removed from the magnetic field an induced magnet loses most/all of its magnetism quickly. |
|
What happens to an induced magnet when it's removed from the magnetic field? |
|
|
|
Students should be able to describe the attraction and repulsion between unlike and like poles for permanent magnets |
|
How do the poles of the magnets interact? |
|
|
|
Students should be able to describe the difference between permanent and induced magnets. |
|
What is the difference between permanent and induced magnets |
