The magnetic force, F=qvxB, on a charged particle moving in a magnetic
field is typically introduced in the second semester of the introductory
physics sequence. When presented to students, it is often assumed that the
velocity of the charge used in this calculation is relative to the magnetic
field in which it travels. Here we demonstrate with a couple of gedanken
experiments the actual relativity of the magnetic force and to what the
charge’s velocity is relative.

Organized by the American Association of Physics Teachers (AAPT) and funded by member
societies of the American Institute of Physics and other generous donors, this physics
community initiative encourages excellence in physics education while rewarding outstanding
physics students.
Each year high school students compete in
the F
=ma exam contest in early January. Top
scorers advance to the semi-final round. AAPT
then uses the semi-final exam to recruit those
students most qualified to compete in the Annual
International Physics Olympiad (IPhO).
This year the IPhO will be held in
Copenhagen, Denmark, July 7–15, during our
Summer Meeting. Find info at:
