AMPERE’S RULE APPARATUS
- Ampere’s Law describes the direction of a magnetic field around a current-carrying wire. The magnetic field generated by an electric current flowing in a conductor is always at right angles to the direction of the current flow.
- This is always demonstrable by Ampere’s Right Hand Thumb Rule.
- Our apparatus consists of a thick brass wire bent at right angles to form two straight sections, one horizontal and one vertical.
- The ends of this wire have screw terminals for attaching wires to connect the apparatus to a current source.
- This is arranged on a clear plastic base.
Also included in this apparatus are:
- 1 large compass with a diameter of 45mm and
- 6 small compasses, each with a diameter of 16mm.
Students can investigate and get a better understanding of the effect of the direction and the intensity of the current and the resulting magnetic field that is created around a wire. They can correlate it with Ampere’s Right Hand Thumb rule.
