Key Questions:

1. What are the poles of a magnet?
   • The poles of a magnet are the places where the magnetic Forces are strongest.
2. What is the magnetic field?
   • 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.
3. What force is always between a magnet and a magnetic material?
   • The Force between a magnet and a magnetic material is always one of attraction.
4. What happens when two magnets are brought close together?
   • When two magnets are brought close together they exert a Force on each other.
5. What does the strength of the magnetic field depend on and where is it the strongest?
   • The strength of the magnetic field depends on the distance from the magnet. The field is strongest at the poles of the magnet.
6. What happens when two like poles are brought together?
   • Two like poles repel each other.
7. What affects the direction of the magnetic field?
   • 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.
8. What happens when two unlike poles are brought together?
   • Two unlike poles attract each other.
9. What direction does the magnetic field line go in?
   • The direction of a magnetic field line is from the north (seeking) pole of a magnet to the south(seeking) pole of the magnet.
10. What type of force are attraction and repulsion between magnetic poles examples of?
    • Attraction and repulsion between two magnetic poles are examples of non-contact Force.
11. What causes a magnetic compass to follow the direction of the Earth's magnetic field?
    • 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.
12. What is a permanent magnet?
    • A permanent magnet produces its own magnetic field.
13. How can a plotting compass be used to plot the magnetic field pattern of a magnet?

14. What is an induced magnet?
    • An induced magnet is a material that becomes a magnet when it is placed in a magnetic field.
15. What force does induced magnetism always cause?
    • Induced magnetism always causes a Force of attraction.
16. Why does a compass point North?
    • The core of the Earth is magnetic.
17. What happens to an induced magnet when it's removed from the magnetic field?
    • When removed from the magnetic field an induced magnet loses most/all of its magnetism quickly.
18. How do the poles of the magnets interact?
    • Repulsion occurs between unlike and like poles for permanent magnets.
19. What is the difference between permanent and induced magnets
    • Induced magnets can be switched on and off unlike permenant magnets.
