Electromagnetic Induction
... a steady magnetic field will not cause a current to flow in a circuit. It is a time changing magnetic field that “induces” a current to flow. The changing magnetic field produces an electric field which is not conservative. The line integral of the electric field around a loop or circuit is not zero ...

Representing Vector Fields Using Field Line Diagrams
... An array of field lines is called a field line diagram, and it is a way of representing both the direction and the strength of a vector field. The direction is found by focusing on an individual field line, as above. The strength is found by looking at the density of field lines. For example, the fi ...
