- The Hall Effect
- When a conducting strip carrying a current i is placed in a uniform magnetic field B, some charge carriers (with charge e) build up on one side of the conductor, creating a potential difference V across the strip. The polarities of the sides indicate the sign of the charge carriers.
- Orientation Energy of a Magnetic Dipole
- The orientation energy of a magnetic dipole in a magnetic field is
- If an external agent rotates a magnetic dipole from an initial orientation θi to some other orientation θf and the dipole is stationary both initially and finally, the work Wa done on the dipole by the agent is
