The force on a charged particle in a magnetic field is very different from the force due to an electric field. Please list as many differences as you can. Don't forget to include differences in the direction as well as the magnitude.

Estimate the force of the earth's magnetic field on a 10 cm segment of a typical wire in your home.
Hint: the magnitude of the Earth's magnetic field is about 5.5 x 10^-5 T.

A proton moving downward enters a region of space with magnetic field B which points eastward. In which direction is the force on the proton?

Two long parallel wires are separated by 0.2 meters and carry currents of 3 and 5 amps as shown in the figure. What is the direction of the magnetic force felt by the wire on the right? By the wire on the left? How will the magnitudes of these forces compare?

Let's say you shuffle across a carpet on a dry winter day, and pick up a charge of 5 microcoulombs. What force will you feel due to the magnetic field of the Earth?

The magnetic field can often be calculated easily by using Ampere's law. This law is similar to Gauss' Law, where we had to use an "Gaussian Surface." Now, we must use an imaginary "Amperian loop." What are the essential features of an Amperian loop?

You can make a good approximation to a "long solenoid" by buying a 50 yd. spool of wire and winding it carefully (nice, even coils) around a cylindrical core (say a broomstick), then removing the core. Estimate the maximum magnetic field that can be produced in such a solenoid.
