Question 1

A 105 A current circulates around a 1.60-mm-diameter superconducting ring. Part A v What is the ring's magnetic dipole moment? Express your answer in amper-meters squared with the appropriate units. View Available Hint(s) A = 2.11*10-4 A . m2 Submit Previous Answers Correct Part B What is the on-axis magnetic field strength 6.00 cm from the ring? Express your answer with the appropriate units. View Available Hint(s) B = 2.4 . 10-7 T Submit Previous AnswersThe two insulated wires in (Figure 1) cross at a 307 angle but do not make electrical contact. Each wire carries a 5.0 A current. Points 1 and 2 are each 4.2 cm from the intersection and equally distant from both wires. Figure 1 0f 1 * PartA What is the magnetic field at point 17 Express your answer in microteslas. Enter your answer as positive if the magnetic field is directed into the page and as negative if the magnetic field is directed out of the page. View Available Hint(s) bEIEMR & O = 7 The element niobium, which is a metal, is a superconductor (i.e., no electrical resistance) at temperatures below 9 K. However, the superconductivity is destroyed if the magnetic field at the surface of the metal reaches or exceeds 0. 10 T. Part A What is the maximum current in a straight, 3.60-mm-diameter superconducting niobium wire? Express your answer with the appropriate units. ?
