Applications of the magnetic needle with brass cup bearing
Placed on a pivot, the needle turns until it lies along the magnetic field at that point, which makes it useful for locating north and south, exploring the field of a bar magnet and detecting the field around a wire that carries a current.
- Finding the magnetic north–south direction in the classroom
- Exploring the field pattern around bar and horseshoe magnets
- Detecting the magnetic field around a current-carrying conductor
- Group activities in which each bench needs its own pivoted needle
