How far is the electron above the wire

Reference no: EM1355213

Q. A straight horizontal wire carries a current of 6.50 μA. An electron is moving above the wire a direction parallel to it and in the same direction as the conventional current in the wire, at a constant velocity of 5.41×105 m/s. Assume that the force of gravity acts on the electron and that the electron is moving parallel to the Earth's magnetic field, so that the only magnetic force on it comes from the field generated by the current in the wire. (a) What is the magnitude of the upward force that the magnetic field must exert on the electron to keep it at a constant velocity? (b) How far is the electron above the wire?
