What is your plan for the electromagnets? If you can not find them, they are
simple to make yourself out of fine insulated (varnished) copper wire. You
will have to do a little bit of experimenting to get the streingth just

have, the more streingth you will have. A certain amount of turns is
required to prevent drawing excess current and burning out the wire and/or
power supply.

| IMHO is the easiest way to get strong electro-magnets to disassemble 6V relays. They include good electro-magnets. I did so and was able to hold a 500g hammer with two of them running at 6V. I used relays from FINDER (Series 55 if i remember right), (...) (23 years ago, 11-Dec-01, to lugnet.robotics)
