A circular loop of radius r = 0.060 m and resistance R = 0.209 is in a region where there is a spatially uniform magnetic field, as shown in Figure. The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value | B| = 9.0T and is dB decreasing at a rate of -0.560 T/s. dt a) Is the induced current in the loop clockwise or counterclockwise? Motivate your answer to get any point. b) What is the rate at which electrical energy is being dissipated by the resistance of the loop? O O B

A rectangular loop of wire is moving toward the bottom of the page with a speed of 0.020 m/s. The bottom part of the loop is outside the region. The field strength inside the region is 2.4 T and the magnetic field outside the region is and the magnetic field outside the region is zero. The width of the loop is 0.080 m and the length is 1.0 meter. What is the current induced in the wire if the resistance of the loop is 0.12 ohm?

A neurologist is using a device, with a thin circular coil of current-carrying wire of radius 1.3 mm, to stimulate neurons in a patient's brain. The coil is placed directly against the patient's skull, anc everywhere within the area of the coil, the magnetic field changes from zero to 1.50 T (perpendicular to the plane of the coil) in 100 ms. What is the magnitude of the average emf induced around the circumference of this circular area in the brain? Express your answer in units of mV. mV Need Help? Read It Submit Answer

Near San Francisco, where the vertically downward component of the earth's magnetic field is 6.4 x 10-5 T, a car is traveling forward at 24 m/s. The width of the car is 2.4 m. Find the emf induced between the two sides of the car. If positive charge accumulates on the driver's side, the enter the emf as a positive number. If negative charge accumulates on the driver's side, the enter the emf as a negative number.
