how do you find the Conventional current for the last problem and also the magnitude of the magnetic force.. any help would be appreciated

Remember that conventional current flows from + to - and opposite to electron current. Magnetic force is either F = q (v x B) or F = I (L x B). Use right hand rule for direction.

you have to solve the laplacian and write down some nifty matrices and do a little dance.

I used the formula 0=vbl-IR
and that gave me the wrong answer for I, I know that it flows from + to - but the formula is what I am getting wrong

doesn't your class have a messageboard on wolfware?

nobody uses it. There are two questions sitting on there with no answers. It's a real shame, too, because I don't understand this stuff.
