Good afternoon,
I am carrying out a practical magnetism project which involves 2 small (2mm x 2mm - 0.6kg) neodymium magnets attached together, and an electromagnet to create a push-pull force from below in order to part them. For those that also build model railway/railroads, this will be a bespome wagon coupling system, and the electromagnet would be used as an uncoupling device. I have uploaded a picture explaining what I am attempting to achieve. The question concerns the power/pull size of the sucked electromagnet required to force the permanent magnets apart from around 10-20mm below the attached magnets. I have tried a 12v 2.5kg sucked electromagnet and it had zero effect even when almost touching the other magnets. Any assistance would be greatly appreciated. This is for my own personal use and will not be used for commercial gain.
