The electrons flow forever because there is zero resistance, the kinetic energy is effectively the potential you apply to the superconductor. From then on there is no resistance so there is no loss. Think of it like water in a circular pipe (cliche) if you add water into a pipe that had no...

I mean the art of a spin bowler in cricket one that imparts rotation on the ball which causes drift in the air and then also a turn when the ball grips the pitch(ground) but I'm mostly interested in the amount of drift i.e deviation from a straight line through the air due to the rotation of the...

Hi, I'm just trying to find out if there is a calculation to that relates deviation from a straight line to the forward velocity and the rotation of a circular object. Essentially i have a small project that i get to prepare and work on and was thinking of trying to find the optimal bowling...

Homework Statement Just a question when determing the B-field inside the volume of a toroid as a function of its radius. Does it change the problem if the toroid has a non circular cross section i.e a square rather then a circle?
