Hello - I have attached a drawing of a simple system that I've been working on. I have a plastic base with a neodymium magnet recessed into the top. There are small ridges protruding from the top of the plastic base. A piece of thin steel will be attracted to the magnet and lay on top of the ridges. I was wondering if it is possible to install a small electromagnet on top of the neodymium magnet such that when the electromagnet is activated, it repulses the neodymium magnet and allows the steel plate to be removed. My thought is that the electromagnet can be strong enough to repulse the neodymium magnet, but weak enough to allow the steel plate to be removed with minimal energy.
Is something like this possible? Thanks very much. I appreciate the help.
