I am using a self-built electromagnet in my project that consumes 9.0 amps at supplied voltage of 12 VDC. I don't mind even if amps goes high. The power supply I am using can provide up to 30 amps. I have to experiment with providing an oscillating power supply to electromagnet.
I want to use IC 555 timer for that purpose. But IC 555 timers that I searched appear to have output 200 mA. Is there any 555 timer that provides high current what I need OR is it possible to use same 555 timer with some external equipment for that. Any sources or tutorial for that will also be very helpful.
