Magnetic forces are non-contact forces. Magnets can be attracted to or repel other magnets.
Magnetic forces arise between electrically charged particles due to their motion
The direction of a force on a wire in a magnetic force can be found using Fleming's left-hand rule.
When two parallel wires are placed close to each other they exert a force of attraction or repulsion on each other, depending on the directions of the currents within the wire.
For a conductor at right angles to a magnetic field and carrying a current: F = BIL
