A long solenoid (cross-sectional area = 0.79 x 10-6 m2, number of turns per unit length = 3523 turns/m) is bent into a circular shape so it looks like a doughnut. This wire-wound doughnut is called a toroid. Assume that the diameter of the solenoid is small compared to the radius of the toroid, which is 0.041 m. Find the emf induced in the toroid when the current decreases from 2.5 A to 1.1 A in a time of 0.15...
3. Find the magnitude of the induced electric field outside a long solenoid at a distance rZR from its central axis if the solenoid is of radius R and hasn turns of wire per unit length and carries a time-varying current that varies sinusoidally as l = 1-cos cot where I-is maximum current and ω is the angular frequency of the current source. 4. A rectangular coil of N windings had an emf of 40 mV induced in it wher...

A long solenoid (cross-sectional area = 1.10*10^-6 m^2, number of turns per unit length = 2544 turns/m) is bent into a circular shape so it looks like a donut. This wire-wound donut is called a toroid. Assume that the diameter of the solenoid is small compared to the radius of the toroid, which is 0.052 m. Find the emf induced in the toroid when the current decreases to 1.3 A from 2.7 A in a time of 0.14 s. The...
1. a. One solenoid is centered inside another. The outer one has a length of 47.0 cm and contains 6700 coils, while the coaxial inner solenoid is 5.00 cm long and 0.170 cm in diameter and contains 17.0 coils. What is the mutual inductance of these solenoids? The current in the outer solenoid is changing at 38.0 A/s. b. Find the emf induced in the inner solenoid. c. A toroidal solenoid has a mean radius of 18.0 cm and a...
