How do i make a coil?
The might sound a bit childish but i want to know about a coil. I am currently making a voltmeter(analog).I need to make a coil for it. I have a magnetic wire(around1.5 meters).Every time I make a coil out of it and supply it with power the battery shorts. I get no responce from the coil(like it does not attracts or repels a magnet or nail).So how do make a correct coil for my voltmeter and how do i know weather it responces.
