Lesson 22: Ch. 29.1-29.2, Magnetic Field Due to a Current
1) Four electrons have velocities as shown below. For each electron, draw an arrow representing the direction
of the magnetic force exerted by the wire on the electron.
2) Two infinitely long wires each carry a current i = 4.0 A. What is the magnitude of the magnetic field at
point P if d1 = 6.0 m and d2 = 4.0 m?
3) In the figure below, a = 0.27 m, b = 0.12 m, θ = 80◦ , and i = 0.37 A. What is the magnitude and direction
(into or out of the page) of the magnetic field at point P ?
