A 13-cm length of wire is held along an east-west direction and moved horizontally to the north with a speed of 2.2 m/s in a region where the magnetic field of the earth is 55 micro-T directed 28° below the horizontal. What is the magnitude of the potential difference between the ends of the wire? Write your answer in micro-volts.

Problem 5. Consider an infinite metal sheet that carries a uniform current per unit width (where the width is defined perpendicular to the direction of the current) of 0.052 A/m. Use Ampere's law to find the magnitude of the magnetic field on each side of the plate.

A negatively charged ion with an excess electron moving with a velocity vx = 1.095 x103 m/s is introduced into a magnetic field Bz = 4 mTesla perpendicular to the ion’s direction of motion. The ion travels in a semi circle of diameter d = 8 cm before striking a detector. What is the ion?

Two long, parallel wires carry currents of I, = 2.78 A and I, = 4.70 A in the direction indicated in the figure below. (Choose the line running from wire 1 to wire 2 as the positive x-axis and the line running upward from wire 1 as the positive y-axis.) P I (a) Find the magnitude and direction of the magnetic field at a point midway between the wires (d = 20.0 cm). magnitude direction 270 ° from the positive x-axis (b) Find the magnitude and direction of the magnetic field at point P, located d = 20.0 cm above the wire carrying the 4.70-A current. magnitude direction ° to the left of the vertical Viewing Saved Work Revert to Last Response
