Lenz's Rule and Ferromagnetism

[QUOTE="Dale, post: 6474194, member: 43978"] Lenz’s law does work with a ferromagnetic object. The key principle demonstrated in this video is actually eddy currents being formed through Faraday's law and Ohm's law. Lenz's law is just the minus sign in Faraday's law, which is what makes it so that the eddy currents work to slow the motion rather than to accelerate it. For ferromagnetic objects the conductivity is lower so eddy currents are smaller. Also, ferromagnetic objects are usually not a good shape for forming large eddy currents. So the result is that ferromagnetic objects often become projectiles instead of moving slowly. [/QUOTE]
