Magnets and Magnetic Fields
Magnets
Lines always go north to south and show which way a force acts on north pole
Closer the lines, stronger the field
Magnetic field lines show a magnetic field
Further away from the magnet you get, weaker the field is
Have two poles - north and south
Magnetic field is strongest at poles of a magnet
Produce magneti fields
Magnetic forces are strongest at the poles
Magnetic fields
Like poles will repel eachother
Two unlike poles will attract eachother
Can be attractive or repulsive
Placing north and south poles near each-other creates a uniform field
Causes forces between magnets
Magnetic field is the same strength everywhere between the poles
Plotting compasses
Can use a compass to build up a picture of what the field looks like
When they're not near a magnet, compasses point towards north pole. This happens because the Earth generates its own magnetic field
Inside compass is a tiny bar called a needle
Earths core is magnetic
Show directions of magnetic field
