PHYS 2002 Chapter : Physics 2002 Exam Review 2
Document Summary
Wavelength: a long straight wire is held fixed and carries a current i as shown. A rectangular conducting loop is sitting to the left of the wire and is free to move. If the current in the wire is decreased to zero, what happens: the loop moves up, the loop moves down. Loop 1 swings back and forth like the bob on a pendulum, loop 2 rotates about a vertical axis, and loop. 3 oscillates up and down on a spring. 2: loop 1 only, loop 2 only, loops 1 and 2, loops 1 and 3, all three loops. B 3: a conducting ring is dropped straight down in a region of space where a uniform magnetic field exists into the page. At the instant shown in the figure, the ring is leaving the magnetic field, i. e. half the ring is in the field and half the ring is out.
