6.7 Uniform Magnetic field

Know how to use two permanent magnets to produce a uniform magnetic field pattern

If the lines of a magnetic field are close together the magnetic field is strong, likewise further apart magnetic field lines show a weak field. If the magnetic field lines are parallel to each other we have a field of constant strength – a uniform field

Making a Uniform magnetic field
An easy way to produce a roughly uniform magnetic field is to hold two opposite poles close to each other so that they attract [see image below].
