Investigating the effect of the magnetic field from a wire on a compass
Sytil Murphy
This apparatus has two primary applications. The first is in teaching the concepts of resonance in the context of magnetism, which can be applied to the teaching and understanding of magnetic resonance imaging. The second investigates the direction of the field around a current carrying wire and the superposition of magnetic fields. The compass deflection angle can be measured as a function of the distance from the wire and compared to theory.
