I have a small electromagnet whose polarity needs to be switched at 50Hz (using a 555 timer?), the DC current to the electromagnet is a 12 volt battery.
My knowledge of electronics is very basic, I have not done anything in this field for at least 35 years!!! So please go gently on me. Even better, if someone in the UK fancies putting this together for me at a sensible cost then I will be forever grateful!
