A solenoid of length 55 cm has 280 turns of radius 2.4 cm. An outer coil with 14 turns of radius 5.2 cm is placed around the solenoid. The axes of the coil and solenoid coincide. Find the magnitude of the emf induced in the coil if the current in the solenoid varies according to I = 6sin(60πt) A. cos (60mt) mV outer coll solenoid

A long solenoid has a length 7.9-m, radius 3.5-cm, and 370 turns. It surrounds coil of radius 6.9 meters and 73 turns. If the current in the solenoid is changing at a rate of 710-A/s, what is the magnitude (absolute value) of the emf induced in the surrounding coil? |emf|= = V (Show at least 2 significant figures.)

A 1.95 m length of wire is held in an east-west direction and moves horizontally to the north with a speed of 14.8 m/s. The vertical component of Earth's magnetic field in this region is 40.0 µµT directed downward. Calculate the induced emf between the ends of the wire and determine which end is positive. magnitude mv positive end ---Select-- v Need Help? Read It

9:49 LTE Send a chat 3. A solenoid consists of 400 turns per centimeter and the radius of windings is 1.382X102 m. Current through the solenoid is increasing at a rate of 4.8X10 A/min. A 10 turn (pickup) coil is wrapped tightly around the circumference of the solenoid. The ends of the (pickup) coil are connected to a 1.52 resistor. Determine the current induced in the coil. solenoid T. 1.50 coil • Previous

In the figure below, a semicircular conductor of radius R = 0.220 m is rotated about the axis AC at a constant rate of 170 rev/min. A uniform magnetic field of magnitude 1.32 T fills the entire region below the axis and is directed out of the page. R Воли (a) Calculate the maximum value of the emf induced between the ends of the conductor. (b) What is the value of the average induced emf for each complete rotation? (c) How would your answers to parts (a) and (b) change if the magnetic field were allowed to extend a distance R above the axis of rotation? (Select all that apply.)
