Hello everyone
I am trying to create a ring shaped magnet. If you coil wire around a toroidal core the magnetic field is only inside the toroid I want the magnetic field to be present around the outside and inside the hole of the toroid, the ring shaped magnet? I basically want the magnetic field of my toroid to be pretty close to the magnetic field of a round cylinder shaped permanent magnet. So is there any way to coil a wire around a toroid or magnetize a steel or iron core so the magnetic field matches that of a circular permanent magnet? Would having two separate wires and criss cross them around the toroid create the field I want? I even tried leaving a good bit of room between coils but the magnetic field was not strong enough to see if the magnetic field is the way I want it. I do not know what else to try. Any advice? I am using AWG magnet wire, the three color pack from Radio Shack, a steel core, a 12v 3 amp dc power supply, and I would like to know how to coil the wire around the toroid to make the field present around the outside and inside the hole of the toroid just like a circular permanent magnet?
Thanks
Stephen
