PHY222 Lab 10 - Magnetic Fields: Magnetic Flux and Lenz`s Law
... 0.3 Lenz’s Law Lenz’s Law is part (c) of the following series of statements. (a) If a magnetic flux through a coil of wire changes, a current will flow in the coil. (This current is known as an induced current. The changing flux induces current to flow.) (b) The flowing current creates its own magne ...

... Lenz's law states that the direction of an induced emf is always such as to act against the change that causes the induced emf. To understand Lenz's law, consider an open coil connected to a centre-reading meter. The meter pointer deflects in a certain direction when a bar magnet is pushed into the ...
