PLEASE EXPLAIN WITH CALCULATIONS
What is the (a) “current” due to the electron orbiting in a circular path about the proton in a hydrogen atom? Take the orbital radius to be r = 0.0529 nm.] (b) What magnetic field strength does this “electron current” create at the proton location? (c) If the electron is orbiting clockwise, as viewed from above its orbital plane, what is the direction of this field?
