Topics covered:
- Maxwell's equations
- Metal loop
- Flat coils
- Biot-Savart law
- Hall effect
Principles and objectives:
The spatial distribution of the field intensity between a pair of coils in the Helmholtz arrangement is measured. The spacing at which a uniform magnetic field is produced is studied, and the superposition of the two individual fields to form the combined field of the coil pair is demonstrated. This didactic set allows the following tasks:
- Measure the magnetic flux density along the z-axis of the flat coils when the distance between these coils is a = R (R = coil radius) and when the distance is greater and smaller than the radius.
- Measure the spatial distribution of the magnetic induction when the distance between the coils is a = R, using the rotational symmetry of the setup: a) measurement of the axial component Bz; b) measurement of the radial component Br.
- Measure the radial components B'r and B"r of the two individual coils in the median plane between them and demonstrate the superposition of the two fields: Br = 0.
Comments:
Particularly homogeneous magnetic field and high flux density due to the large diameter of the Helmholtz coil. Helmholtz coils are suitable for multiple other elementary experiments.
