Max,
An electromagnet would not produce interference with the radio modem in and of itself. Big coils do have this natsy habit of producing an arc at the switch when you try to remove current from the coil. That arc is capable of a lot of energy in the RF range and might be enough to disrupt the modem.
As to your closing signature, another form I heard "way back when" relates to the F104 fighter. Marines were heard to say it proved if it you put a big enough engine on it, you could get a brick to fly.
