Question

Two rings each have a current I 1.0 Amp running through them. One has a radius 1.0 cm, the other 2.0 cm. a) Place them so they are concentric with each other, both have current in clockwise direction. Find the magnitude and direction of the magnetic field at the center of the rings. b) Rotate the small ring 90 degrees so that from above, you o on the right. Find the magnitude and direction of the magnetic field at the center of the rings. c) Rotate the small ring 90 degrees more so that the two rings have currents in opposite directions. What does the current have to be of the small loop (keep large loop the same) so that the magnetic fields cancel at the center? d) If an electron was dropped through the center of the rings in part a, how would the electron be nly see the edge that was previously deflected by the magnetic field?

    A current is set up in a wire loop consisting of a semicircle of radius 4.52 cm, a smaller concentric semicircle, and two radial straight lengths, all in the same plane. Part (a) of the figure shows the arrangement but is not drawn to scale. The magnitude of the magnetic field produced at the center of curvature is 47.19 T. The smaller semicircle is then flipped over (rotated) until the loop is again entirely in the same plane (part (b)...
