Thanks sophie. Let's say 5A more or less. I'm not sure what the inductance would be but the coils will be on say 15cm ferrite rods for varying amounts of wire. Sorry I'm no expert. I have DC power supplies, could I buy another device that would connect up with it to vary the power output?

Hi, What hardware do I need to buy if I want to pulse DC power, say 12v through some regular coils with iron cores. Can I use a regular power supply connected to some other device? How would I pulse the output of the power supply?
