Yes, you can use an electromagnet with the RCX. Depends on what you want to do with it, but it should work. The device from a disk drive might be a 12 volt device, or 5. The RCX puts out around 8-9, so either way the device isn't drawing the correct (...) (19 years ago, 16-Jan-07, to lugnet.robotics.nxt)
