I am in the final stages of making an Adams motor.

I wish to constuct a 12 to 24 DC pulse coil that will be powerfull and
efficient repelling a 7/16 inch (diameter) neodymium rod magnet.

Can anyone give me advice as how to construct this coil. My power
supply is a regulated 12 volts DC and puts out 2.5 amps. I plan to use
24 volts DC later so the coil should be able to handle that also. Any
and all advice is most welcome. Thanks, Tom
