The orbit of a charged particle in a uniform magnetic field |
Description |
A magnet is an element whose net magnetic moment is different from zero. In this experiment we calculate the magnetic moment of a magnet by measuring the oscillations of the magnet in an almost constant magnetic field. We also perform the Thomson experiment to calculate the ratio charge/mass for an electron. |

Magnetic
Fields and the Force on a Charge:
The Magnetic Field applet is designed to allow users to examine the effects of a magnetic field on a charged particle.
This animation shows the magnetic field of a Helmholtz coil when the current in the top and bottom coils flows in the same direction.
