A horizontal wire carries a current straight toward yon From your point of view, the magnetic field at a point directly below the wire points directly away from you. to the led. to the right. directly toward you. vertically upward. An electron enters a magnetic field of 0.75 T with a velocity perpendicular to the direction of the field. At what frequency does the electron traverse a circular path?(mcl - 9.11 times 10-31 kg, e-1.60 times 10 -19C) 2.1 ? 1010Hz 4.8" 1010Hz 2.1 times 1014Hz D)4.8 times 10-11 Hz A thin copper rod that is 1.0 m long and has a mass of 0.050 kg is in a magnetic Held of 0.10 T. What minimum current in the rod is needed in order for the magnetic force to cancel the weight of the rod? 1.2 A 2.5 A 4.9A 7.6A 9.8 A Two long parallel wires carry currents of 10 A in opposite directions. They are separated by 40 cm. What is the magnitude of the magnetic field in the plane of the wires at a point that is 20 em from one wire and 60 cm from the other?(mu0 = 4pi times 10-7 T m/A) 1.5 muT 3.3 muT 6.7 muT 33 muT 67 muT Three panicles travel through a region of space where the magnetic field is out of the page, as shown in the figure. The electric charge of each of the three particles is. respectively. I is neutral 2 is negative, and 3 is positive. I is neutral 2 is positive, and 3 it negative. I is positive. 2 is neutral and 3 Is negative. I is positive. 2 is negative, and 3 is neutral I is negative. 2 is neutral and 3 is positive. A coil lies flat on a table top in a region where the magnetic field vector points straight up. The magnetic field vanishes suddenly. When viewed from above, what is the direction of the induced current in this coil as the field fades? counter-clockwise then clockwise clockwise then counter-clockwise clockwise counter-clockwise There is no current induced in the coilExplanation / Answer
