Helmholtz Coils are a special arrangement of coils that are placed in such a way as to generate a very uniform magnetic field between them when a current is applied.  The strength of the magnetic field is proportional to the number of turns in the coils and the current applied to them.  

The PASCO Helmholtz Coils setup consists of two field coils mounted on a base to provide a uniform magnetic field between the coils. The base has a slot that allows the coils to be spaced apart at any distance from 3 cm to 20 cm (center-to-center distance). The proper separation for Helmholtz coils (i.e., the radius of the coils) is marked on the base. Two 0.635 cm (0.25 inch) diameter holes between the coils accommodate mounting devices in the uniform magnetic field.

Buying Guide

500 Turn Field Coil

Individual field coils are available for customers who only have the base, need replacements or have the 200-turn coils and would like to see the change made using the 500-turn coils or vice versa.
