- 4where, on like and unlike magnet patterns, is the magnetic field uniform.On like magnets the field is uniform in the centre of the gap.
On unlike magnets the field is uniform going away from the magnet ends pointing towards eachother. - 5how is a magnetic field produced around a wire?when a current flows through the wire.
- 6apperance of field around a wireconcentric circles, oerpendicular to the wire.
- 7how do you reverse the direction of the magnetic field?reversing current reverses the direction of the magnetic field
- 8Left hand rule
