... The second method works because the magnetism in the electromagnet comes from the total amount of current flowing around the nail. If there is 1 amp of current in the wire, each loop of wire adds 1 amp to the total amount that flows around the nail. Ten loops of 1 amp each make 10 total amps flowing ...

... neglect the discreteness of charge and treat it as a continuously varying quantity -- the same as we do with mass. The SI unit of charge is the coulomb, abbreviated C. The charge of a single electron is 1.60219×10-19C, or put another way, -1.0C of charge contains 6.24×1018 electrons. While much less ...
