thanks a lot, from this point it's not very hard to find the equations... I'm an expert at trivial errors, so wish me luck...

Using the stuff above, I've obtained a system of differential equations, but I don't know if it is correct... I want to use Newton's second law, F=ma, being \vec{F}=q( \vec{E} + \vec{v} \times \vec{B}) the Loretz force that acts on the electron (of charge q and mass m). Velocity in...

Allright. Using Gauss's law and Ampere's circuital law it's easy to obtain the fields (in cylindrical coordinates, with the vertical axis fixed at the conductor's axis and oriented in the current's direction): \vec{B}=\frac{\mu_0 I}{2 \pi r}\hat{\phi} \vec{E}=\frac{\lambda}{2 \pi...

Hello, I'm new on this forum :) I seriously need help with this problem. It has to be perfect if I want to pass the course, so I will really appreciate any solution to check my results. ---- An electrical current of 100[A] runs through a cilindrical conductor (radius 0.01[m], infinite...
