555581 Helmholtz Coils with Holder and Measuring Device for Fine Beam Tube

Helmholtz Coils with Holder and Measuring Device for Fine Beam Tube For generation of a homogeneous magnetic field for the e/m determination with the fine beam tube (555 571). The holder supports the fine beam tube and provides the electrical connections to the tube. A measuring device with mirror and two riders for measuring the diameter of the electron beam when it is made to follow a circular path is included.
