    How can Lenz's Law be derived?

    Yes, I am asking for some sort of mathematical proof. But what you say is reasonable, and I see where you are coming from. Let's say a magnetic dipole is moving toward a coil with a constant velocity. I was mainly wondering if the part of Lenz's Law that says the induced magnetic field will...

    How can Lenz's Law be derived?

    Heinrich Lenz postulated in 1834 the following law; "An induced current is always in such a direction as to oppose the motion or change causing it" I have checked many undergrad/grad-level textbooks for a derivation, but they all just state Lenz's Law without derivation as if it were a...

    Electromagnetic Radiation from a Rotating Magnet

    I know that accelerated charges give off electromagnetic radiation, but does an accelerated (spinning) magnet give off electromagnetic radiation as well? If so, what is the energy loss from the magnet's kinetic energy?
