A single loop of nickel wire, lying flat in a plane, has an area of 9.00 cm and a resistance of 1.50 0. A uniform magnetic feld points perpendicular to the plane of the loop. The feld intaty has a magnitute of 0.500T and the magnitude increases linearty to 2.00 Tin a time of 1.10s What is the induced current (in mA) in the loop of wire over this time

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.

Near San Francisco, where the vertically downward component of the earth's magnetic field is 5.7 x 10-5 T, a car is traveling forward at 30 m/s. The width of the car is 2.3 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. Number i Units

A 2.80-m length of wire is held in an east-west direction and moves horizontally to the north with a speed of 0.370 m/s. The Earth's magnetic field in this region is of magnitude 50.0 µT and is directed northward and 53.0° below the horizontal. (a) Calculate the magnitude of the induced emf between the ends of the wire. (b) Determine which end is positive. O the east end O the west end O both O neither
