What is the maximum force (in N) on a rod with a 0.100 JC charge that you pass between the poles of a 1.60 T strength permanent magnet at a speed of 4.90 m/s? NAn electron in a television tube moves with a speed of 6.50 x 10' m/s, in a direction perpendicular to the Earth's field, which has a strength of 5.00 x 10- T. (a) What strength electric field must be applied perpendicular to the Earth's field to make the electron move in a straight line? kv/m (b) If this is done between plates separated by 2.00 cm, what is the voltage applied? (Note that TVs are usually surrounded by a ferromagnetic material to shield against external magnetic fields and avoid the need for such a correction.)A rectangular coil with a length of 6.0 cm and a width of 4.0 cm and 250 turns is placed in a uniform magnetic field with a magnitude of 0.70 T. (a) If the maximum torque experienced by the coil is 0.18 N . m, determine the current in the coil. MA (b) When the magnetic field makes an angle of 350 with the normal to the plane of the coil, determine the magnitude of the torque acting on the coil. N ' m
