28. Magnetic Fields and Forces

An electron is moving to the right in a region where the magnetic field points upward. In what direction is the force $F$ exerted by the magnetic field on the electron?

Which description best matches the use of the right-hand palm rule for determining the direction of force on a positive charge moving in a magnetic field?$F$ (force), $q$ (positive charge), $B$ (magnetic field), and $v$ (velocity) are involved.

Which of the following correctly describes the right-hand rule for determining the direction of the magnetic field around a straight wire carrying current to the $\mathrm{right}$?
