iron cores, for my electromagnet motor ? (question).

[nitinnun]

i will also be using the side of the coil,
to both repel and attract the rotor.

like tesla did, on atleast one of his induction motors.


i will not use the EXTREMELY INEFFICIENT monopole method,
which seems to be common in the mainstream.



i made a crude solenoid magnet,
using a different method than above.

it could pick up a pair of steel pliers, if i used the side.
the monopoles on it, couldn't pick up much of anything.


the side of the coil is superior,
for the stator coils of the motor.

Three suggestions:

If the magnetic field or current proximal to the magnetic field to-be-formed is going to be changing, then I would use ferrite which you can craft to you own dimensions - like an epoxy and powdered iron dust mixture.  This will maximize flux and minimize the heat losses. OR, you could create multiple singe non attached out-of-the electrical circuit wires made of steel.  Which brings me to the third suggestion... these wires would have to be insulated though, like floral wire, or regular mag wire can sometimes be purchased in nickel or steel with insulation.  If the current will be continuous on these wires in one direction, it has potential to for a strong field what with it already being ferromagnetic.
