I have made an electromagnet using copper coil of 1.0 mm diameter, iron core of 2 cm dia & 8 cm length for my project. Supplied voltage is 12 VDC and current it consumes is 9.0 Amp. It has 1.5 Ohm resistance. I want to change the polarity of electromagnet like pulsing. I have to control e-magnet pulsing through arduino uno.
I learned H-Bridge is a way to do it. What h-bridge should i use for this amount of current and voltage? What precautions should i take when connecting the H-Bridge to arduino if any? Any other things related to doing changing polarity of e-magnet if pointed out will be of great help for me.
