Physics - The motor effect


Revision notes on the dreadful P3 topic Electomagnetism.

The motor effect

  • The force is:
    (a) Greatest when the wire is perpendicular to the magnetic field
    (b) Zero when the wire is parallel to the magnetic field lines
  • The force is increased by:
    (a) Increasing the current
    (b) Uusing a stronger magnet
  • The direction of the force is reversed id the directpoin of the current or magnetic field…
