So sophicentaur, what if all have is just the wire, magnet, and battery. Is there a way to get a somewhat efficient electric motor out of this besides the basic "scratch the enamel off one side of the axles, connect the current, and position the magnet". Is there somethign i can do to the...

As for what exactly I am working with, here is a general picture of the setup. My idea was just to make a tiny tiny loop to increase the efficiency, since of a larger one.

NascentOxygen and Yungman, that you for replying! I have an update to my question, so I don't think a picture will be needed for this. My professor has told me that basically I can only control one variable of the Magnetic Force equation= qvBsin. I can't really control the B or sin of...

After fixing up the diode direction, here is what i have. (note) the pink wire in the middle is just a reference for where ill be placing a 1-10kOhm resistor. The upper right hand corner shows 2 wires going out of the picture which are attached to a DC motor. The other 2 wires exiting the...

Hey, i actually caught the diode mistake right after i posted the picture! But yes, i have flipped them all to be pointing in an easterly direction now. Glad you saw it and pointed it out!

Yes I can post a picture of everything. For my assignment, all i have to use is one small DC motor, 4 diodes, solderless bb, then just extra enameled copper wire. As for the 12V transformer as a building block in my bb, that i am not sure of. Sorry if i seem like i don't have a grasp on the...

I was told that the place where it says C(subscript)L is where I'm suppose to hook in the motor, because that is the location where both currents are flowing in the same direction( maybe I am completely wrong, which is a constant occurance lol) I guess what i should have asked was, what would...

This is only my second time using a breadboard, so bear with me. I have 4 resistors(black with silver stripe) and one small DC rotating motor. My goal is to get the DC motor to spin, yet I don't understand the diagram that I have including in the posting. Any advice would definitely be...

Gotcha! Ill stick to the more simple "cheap DC motors" haha. Thank you for the help!

I actually would have definitely preferred to build a motor like that, and I actually wanted too, except I'm required for my class to keep the typical simple motor design (much like this one http://www.youtube.com/watch?v=oRSU4FnUSrA&feature=related). The homopolar design does have one...

Okay, so I have a simple D cell battery, enamel coated copper wire loop and a magnet. I can easily get the copper wire loop to spin if I scratch away part of the enamel (that side which touches the stand) off the ends of the wire, run current through a stand, and position the magnet at just the...
