I have a design project coming up and need to make a series of 3 small powerful electromagnets that run off two aa batteries in parallel.
By small I mean no more than 1 inch long by 1/2 inch wide.
What sort of core would be best? Are core shape and size going to make a big diffrenece? will using a fine wire with lots of turns make the magnets stronger?
i've had a look around the net and its been difficult finding info on magnets with low power inputs. Any help would be greatly appreciated.
