WebThe Helmholtz coils of the e=m apparatus have a radius and separation of a = 15 cm. Each coil has N = 130 turns. The magnetic ﬂeld (B) produced by the coils is proportional to the current through the coils (Ihc) times 7:80¢10¡4 tesla/ampere [B(tesla) = (7:80¢10¡4)Ihc]. A mirrored scale is attached to the back of the rear Helmholtz coil. WebIf we compare a single coil and two Helmholtz coils, the magnetic fields differ from each other. The distance from 0.5r to 1.5r showed that the magnetic field decreases as the distance between coils increases. The magnetic field in the graphs is distributed uniformly. References: 1.
