Hi I have tried the question below. However I am failing at the first hurdle part a! Some help and advice would certaintly be appretiated. Thanks Taking a simple model of the hydrogen atom as an electron rotating around the nucleus in a circle or radius 0.53ee-10m at a frequency of 0.66ee16Hz, estimate: a) The look current, b) The magnitude of the dipole-moment of the loop, c) The magnitude and ridection of the magnetic field at a distance of 2ee-9m, from the center of the loop. For part (a) I tried using the formula: I = NevA, however this gave me an answer which was many orders of magnitude wrong lol.
