Hello, firstly, what a great resource.
I am a technical pigmy and am in need of help. I would like to construct a circuit that will magnetise a piece of metal and then cease to magnetise it, rhythmically.
The circuit needs to be small, something I can embed into a cover. The whole thing will be 'docked' and I'm thinking that there would be a contact at the base of the cover which would meet another contact in the 'dock' which would be plugged into a wall plug or perhaps could run off a battery.
I'm sure this can be done, but I don't have the first idea how, what components I would need, how I would put them together.
I need to have a magnetic field that comes on and goes off regularly.
I would be so very grateful for advice, this is for a competition and I have a deadline. If you are kind enough to leave me advice, could you take on board that this is the first time I will have done anything like this. If you could tell me what components I need to buy and what sort of shop I could find the items in, that would be extremely useful.
Many thanks,
the pangolin
