- A uniform magnetic field is perpendicular to the plane of a circular loop of diameter 9.8 cm formed from wire of diameter 2.7 mm and resistivity of 2.41 × 10-8Ω·m. At what rate must the magnitude of the magnetic field change to induce a 11 A current in the loop?A lightning bolt may carry a current of 1.00 104 A for a short time. What is the resulting magnetic field 200 m from the bolt? Suppose that the bolt extends far above and below the point of observation. If possible break it down step by step?AS0.0-g metal ball having net charge Q = 5.50 µC is thrown out of a window horizontally north at a speed v = 22.0 m/s. The window is at a height h = 18.0 m above the ground. A uniform, horizontal magnetic field of magnitude B = 0.0100 T is perpendicular to the plane of the ball's trajectory and directed toward the west. (a) Assuming the ball follows the same trajectory as it would in the absence of the magnetic field, find the magnetic force acting on the ball just before it hits the ground. (Let the +x-direction be toward the north, the +y-direction be up and the +z-direction be east.) B. (b) Based on the result of part (a), is it justified for three-significant-digit precision to assume the trajectory is unaffected by the magnetic fleld? O Yes O No Explain.
