“The induced electromotive force is in such a direction as to oppose, or tend to oppose, the change that produced it.”
“The direction of the induced current produced in a conductor due to the movement of a magnet, or to that of a circuit in which a current is flowing, is always such as, by the action of the induced current on the" magnet or current-conveying conductor, to produce a force tending to oppose the motion.”
An illustration of “Lenz’s law”, wherein a permanent magnet showing moving, to the right at a given velocity, towards a conducting wire, or conceptualized section of copper pipe, which is conductive, but non-magnetic, according to which the movement of the permanent magnetic field will act to produced induced current in the ring, which in turn produced an induced magnetic field, in a direction opposite to the moving permanent magnetic field, thereby slowing or opposing its motion. |
