Hello,
I've been experimenting off and on over the last few months with electromagnets for a specific application. But I seem to have found myself with a big question mark over my head after all of the experimentation I've done.
What I need to create, is a set of four coils, each with more magnetic force than can be found in an N45 Neodymium magnet. Preferably twice as much magnetic force. And each coil should be no larger than a spool of thread and of course, it should be able to be powered from standard home electricity and ideally emit minimal heat from the coils.
What I have found in my pursuits, is that I face walls in that when I obtain what seem to be decent coils, in order to get any kind of decent magnetic strength out of them, I really have to step up the voltage and the current which causes them to get really hot fairly quickly and the magnetic force that I'm getting out of them certainly does not rival or come close to N45 strength.
Common sense tells me that electricity should have the ability to create a magnetic force as strong or stronger than N45 but finding that solution has been a royal pain.
Is there anyone out there with experience in this area who can offer some useful discussion on this topic?
Thank you,
Mike Sims
