Problem 22.17 (Multistep)
A coil of wire is connected to a power supply, and a current
runs in the coil. A single loop of wire is located near the coil,
with its axis on the same line as the axis of the coil. The radius
of the loop is 3 cm.
At time t1 the magnetic field at the center of the loop, due to the
coil, is 0.6 T, in the direction shown in the diagram; the current

Problem 22.26 (Multistep)
In the figure below a very small circular metal ring of radius
r= 0.5 cm and resistance x= 5 Ω is at the center of a large
concentric circular metal ring of radius R= 50 cm. The two rings
lie in the same plane. At t= 3 s, the large ring carries a
clockwise current of 5 A. At t= 3.3 s, the large ring
carries a counterclockwise current of 8 A.

Electric and Magnetic Fields
a) An electron (initially at rest) is accelerated from the
negative plate to a positive plate that is located 20 cm away. The
voltage across the plates is 200 V. What is the velocity of the
electron as it reaches the positive plate?
b) Now if the electron passes through a small hole in the
positive plate (travelling right) and enters a magnetic field (B =
0.5 T) that is directed perpendicular to the direction of...

An electron in a vacuum is first accelerated by a voltage of
31200 V and then enters a region in which there is a uniform
magnetic field of 0.253 T at right angles to the direction of the
electron’s motion. The mass of the electron is 9.11 × 10−31 kg and
its charge is 1.60218 × 10−19 C. What is the magnitude of the force
on the electron due to the magnetic field?
Answer in units of N.

A charge configuration with two
charges of opposite sign but the same magnitude, q, and a
separation distance, d, is called an electric dipole. The
electric dipole moment, or EDM, is a vector, p,
with a magnitude p = qd and a direction from the
negative charge towards the positive charge. When such a dipole is
placed in a region of electric field, it will experience a torque
which depends upon the angle, θ, between the directions of the EDM,...
