A loop of radius r = 6.0 cm is placed parallel to the xy-plane in a uniform magnetic field in the +z direction. The resistance of the loop is 4 Ω. Starting at t=0, the magnitude of the field increases uniformly from zero to 4.2 T in 0.33 seconds. What is the induced current produced in the loop during that time with the correct sign?

A point charge Q moves on the y-axis in the positive direction with a speed of 298 m/s. A point P is on the z-axis at z = 0.05 m. The magnetic field produced at the point P, as the charge moves through the origin, is equal to -1.00 μT

Consider a circular loop of wire. The magnetic field strength at the center of the loop is given by the equation B(t) = [2.0 T/s]t, where t is time in seconds. If the induced electric field outside the loop is |E| = 3.4 V/m at a distance of r = 7.0 m from the center of the loop, find the radius R of the loop. Hint: The result of the line integral of the electric field around the path is E*2

Consider a circular loop of wire. The magnetic field strength at the center of the loop is given by the equation B(t) = [3.0 T/s]t, where t is time in seconds. If the induced electric field outside the loop is |E| = 6.8 V/m at a distance of r = 6.0 m from the center of the loop, find the radius R of the loop. Hint: The result of the line integral of the electric field around the path is E*2

A 4.0-m long conducting wire is formed into a square and placed in the x-y plane. A uniform magnetic field is oriented 30.0° from the plane of the surface of the square with a strength of 10.0 T. What is the magnetic flux through the square? Hint: What are the side lengths of a square with a perimeter of 4.0 m?
