The three loops of wire shown in the figure are all subject to the same uniform magnetic field B that does not vary with time. Loop 1 oscillates back and forth as the bob in a pendulum, loop 2 rotates about a vertical axis, and loop 3 oscillates up and down at the end of a spring. Which loop, or loops, will have an induced emf?

A very long wire and a square loop of wire lie in the plane of the page as shown. Each side of the square is 15 cm in length, the resistance of the loop is 0.6 Ω, and the near side of the loop is 3 cm from the long wire. The current in the long wire is to the right and is increasing. At the moment, the current in the long wire is 6.5 A. The magnetic flux through...
In the figure, a rectangular loop of wire with length a = 3.8 cm, width b = 2.2 cm, and resistance R = 0.70 mΩ is placed near an infinitely long wire carrying current I = 4.7 A
In the figure, a rectangular loop of wire with length a = 3.8 cm, width b = 2.2 cm, and resistance R = 0.70 mΩ is placed near an infinitely long wire carrying current I = 4.7 A. The loop is then moved away from the wire at a constant speed v = 3.9 mm/s, when the center of the loop is at distance r = 7.9 cm, what are (a) the magnitude of the magnetic flux through the loop...

The figure shows two parallel loops of wire having a common
axis. The smaller loop (radius r ) is above the larger
loop (radius R) by a distance x >> R.
Consequently, the magnetic field due to the counterclockwise
current i in the larger loop is nearly constant throughout
the smaller loop.
Suppose that i, the current in the larger loop is shut
off, and decreases at the constant rate
di/dt.
(a) Find an expression for the magnetic flux

1. A square loop of wire with one side of a and resistance R is
placed in a uniform magnetic field of strength B. The field
vanishes and results an induced current I in the loop.
