Introduction.
Current generates magnetic field β of which its direction and magnitude highly depends on the geometry of the coil in which charge flows through. Coils can have different geometric shapes; circular, torus and two circular coils with current flowing in either the same or opposite direction. In such different coil geometry therefore, the magnetic field β can be determined using Ampere’s and Biot-Savart Laws’.
Instruments/apparatus.
- Bar magnet.
- Insulated copper wire Circular and toroidal coil
- Cardboard tube.
- Galvanometer.
Procedure and Observation.
- The insulated copper wire was wrapped around the cardboard tube to form a single circular coil and ...
