If a toy electromagent holds 200 lbs on 2 d cells is that overunity?
If not could someone explain it without just stating the 2nd law of thermal dynamics.
Also if anyone knows the push against and armature in an electric motor compared to the pull of an electromagnet built for lifting there's supposed to be quite a diffirence so why do we make motors this way?
