Magnetic Fields
Physics: AQA GCSE Higher, topic 7.1.4
Magnetic Forces
Magnetic forces (the forces between magnets) are caused by invisible magnetic fields.
Magnetic fields
- Every magnet creates a magnetic field around itself.
- A magnetic field is the area around a magnet where another magnet or magnetic material (iron, nickel, cobalt and steel) feels a force.
Strength of magnetic field
- The strength of a magnetic field depends on the distance from the magnet. The magnetic field is strongest at the magnet’s poles.
