A long straight wire lies along the x-axis carrying 2 A of current in the +x-direction. A second, parallel wire located at y = 20 cm carries current of 5 A in the opposite direction.
(a) What is the magnetic field due to these currents at the point (0, 0.1 m)?
(b) At the point (1m, 1m)?
(c) What is the magnitude and direction of the magnetic force on a 10 μC charge moving in the +z direction with a speed of 104 m/s if it is at the point
