Okay that link actually helped a lot, I was not representing B properly and i forgot I needed the current.

I am working on a lab where we were measuring how magnetic force between two parallel conductors varies with current and the separation between the two conductors. I need to find a formula for the dependence of Force on current to create a fit line on the data in my graph that shows the relation...

At my school I am technically ahead in the math curriculum so I am technically not required to take diff eqs just yet (they recommend you take it 4th semester and multi-variable 3rd, but i took it second) and linear they said you can just get it done whenever so i was thinking about taking...

I am enrolling for classes for next semester and I have the option to take either differential Equations or Linear algebra or both next semester. I have completed Calc 1, 2, and I am completing multivariable this semester. I am a physics major and going into thermo and waves next semester so I...

okay thank you this makes a lot more sense now

it would be 0 correct? because if the magnet is not moving at all the electrons in the coil are not moving

I am currently studying Faraday's law and electromagnets and in class we were told that if you had a coil and say a bar magnet was passed through it the faster the magnetic field was applied to the coil the greater the induced voltage or emf would be. I do not understand why the speed would...
