I have a project I'm working on where I need to have a model train be able to have an electromagnet hold its wheels to the track -- so that it can go "upsides down" and resist derailment.
I'm making the wheels and the track -- so all options are on the table.
If I used a steel track (say 1/4"x1/x4" square stock) and soft iron wheels, what would be the best way to put a coil or coils such that the wheels would be "pulled" to the track? Coils inside the hub of the wheels? just wrap the axle of the train and hope the magnetism transfers? Looking for any ideas and theory on this...
Thanks in advance,
Ted
