• Magnetic fields have direction. As a result we must pay special attention to directions, and vector calculations.



1.1.1 Induction


• The basic property of induction is that it will (in the presence of a magnetic field) convert a changing current flowing in a conductor to a force or convert a force to a current flow from a change in the current or the path.



• We will also experience an induced current caused by a conductor moving in a magnetic field. This is also called emf (Electro-Motive Force)
