To minimize the effects of the magnetic field when needed, the wires carrying current to equipment or appliances are placed close together. Explain how this works to reduce the magnetic field created by the cur-rent in the wire.
Answer to relevant QuestionsTwo circular wire loops are coplanar (that is, their areas are in the same plane) and have a common center. The outer loop carries a current of 10 A in the clockwise direction. To create a zero magnetic field at the center ...If a charged particle moves in a straight line and there are no other forces on it except possibly from a magnetic field, can you say with certainty that no magnetic field is present? Explain. An ionized deuteron (a bound proton–neutron system with a net +e charge) passes through a velocity selector whose perpendicular magnetic and electric fields have magnitudes of 40 mT and 8.0 kV/m, respectively. Find the ...Two identical bar magnets of negligible width are located in the x-y plane. Magnet # 1 lies on the x-axis and its north end is at while its south end is at Magnet # 2 lies on the y-axis and its north end is at y = + 1.0cm, ...A loop of current-carrying wire is in a 1.6-T magnetic field. (a) For the magnetic torque on the loop to be at a maximum, should the plane of the coil be (1) parallel, (2) perpendicular, or (3) at a 45o angle to the ...
