3. Two long wires carry currents I, = 3.0 A, I, = 4.0 A. Each is at the corner of an equilateral triangle 1.0 m on each side. Point P is at the top of this triangle as shown. Take the positive x direction to be to the right (parallel to the base of the triangle), and positive y to be up. a. Find the net magnetic field at point P include 1.0 magnitude and direction. Unit vector notation is acceptable. b. If an electron is travelling with speed 1500 i km/s at the point P, find the force on the electron due to the magnetic field. Again, magnitude and direction of the force are required and you can leave your answer in unit vector notation.

A toroid has a major radius R and a minor radius r and is tightly wound with N turns of wire on a hollow cardboard torus. Figure P31.6 shows half of this toroid, allowing us to see its cross section. If R r, the magnetic field in the region enclosed by the wire is essentially the same as the magnetic field of a solenoid that has been bent into a large circle of radius R. Modeling the field as the uniform field of a long solenoid, show that the inductance of such a toroid is approximately L=120N2r2R Figure P31.6
