SED1002 Helmholtz Coil Experiment

Helmholtz Coil Experiment A helmholtz arrangement consists of a pair of identical coils placed symmetrically along a common axis. A fairly uniform magnetic field can be produced in this setup when they are separated by a distance equal to their radius and having equal currents in the same direction flowing through them. In the present setup, the spatial distribution of the magnetic field of a pair of identical coils in helmholtz arrangement and superposition of the individual fields by the coils is investigated using a digital gaussmeter with axial probe. Features: DC Regulated power supply with safety sockets and dual temperature controlled exhaust fan. Digital Gauss meter with least count of 0.1 Gauss. 4mm Safety sockets and plugs are used to make connection. U channel is used to adjust the distance between the coils Axial probe is used to measure the field in parallel and perpendicular direction. Objectives: To measure the spatial distribution of the magnetic field between a pair of identical coils in helmholtz arrangement. To investigate the spacing between coils at which magnetic field is uniform and to measure its spatial distribution. To demonstrate the superposition of the magnetic fields of the two individual coils Technical Data: Helmholtz Coil Set : Copper, Coil Dia=150mm, N=390, Current 1A (max.) Connection 4mm safety socket.
