how to not short circuit an induction heating coil
Just wondering about induction heating coils and how to not short circuit one.
basically, if i hook up one end of the coil to the positive and one end to the negative (DC) i assume that i will be short circuiting the connection and also creating a crude resistance heater at the same time - which is not what i want to do.
so, how do i avoid this and properly create a induction heating coil that doesn't really (itself) heat up but produces the desired magnetic field that heats the material in the center.
just for the example let's say that I'm using 1/2" copper tubing for the coil and it has 4 turns of an approximately 4" inside diameter and i intend to heat iron scrap in a small ceramic crucible so that i can cast it into 'something'.
thanks
EDIT: I just read that induction coils are AC ... so then could I simply hook up each end of the coil to the bare wires from an extension cord and have it work? or am I going to fry something / myself ??
thanks
