    studying electrical resistance is tough. Why do I have to do it at ohm?

      @awesam17 Electrical resistance isn't that bad, especially if it's in a closed circuit. I actually built an electromagnetic motor last year.

        @northernnarwhal sounds like fun. I wanna do that now

          @awesam17 It's pretty simple. You essentially need to create multiple electromagnets using conductive material and wire coils then position them against each other in a way that the polarity is consistently switching back and forth, then add an axis to create rotation.

            @northernnarwhal wire coils???

              @awesam17 Basically wrap this stuff in the direction of desired magnetism http://paciflexwires.com/wp-content/uploads/2014/09/Bare-Copper-Wire.jpg

            @northernnarwhal by conductive material would you mean copper wire?

              @awesam17 No no no, that's separate. You wrap the copper wire around the conductive material.

                @northernnarwhal OOOOOOOHHH I gettit now. The current magnetises the conductor?

                  @awesam17 Exactly, which is why you need to wrap the copper wire in opposite directions for the separate conductive materials as the direction of current determines the magnetism.

                    @northernnarwhal because of the poles and stuff gotcha

                      @awesam17 I'd also recommend getting insulated wire and scratching the ends so as to reduce static.
