I need an advice on making electromagnet/solenoid from bare copper coil/other option
I have in my lab room thick tinted copper wire. I planned using them to make some electromagnet, but fail to find a solution on how to insulated them. At first I thought using those acrylic/enamel can spray, but I am not sure if it would fully insulated them. Would the acrylic/enamel penetrate between the contact gap and insulated them or will it just fail to do so?
In fact, I am not even sure if it's a good idea to begin with, because I don't want to actually waste the copper.
As an alternate option I thought using those magnet wire from the Microwave Oven transformer, the one with really thick diameter. I would uncoil them, and manually turn them.
I thought I could use some of your advice. Actually, I dont mind if the process takes time, I am just looking a convenient way.
