Electricity/Magnetism Learning Activities

Supplier: VWR Chemicals

Plain borosilicate tubes for insertion of a wire electrode so that the electrode is insulated from the clamp or holder and protected from mechanical damage. The tube also helps the flexible wire electrode be positioned correctly in a rigid support.

Supplier: NATIONAL INSTRUMENTS

The PCIe-6738 is a high-speed, high-density analog output device designed to deliver simultaneous, multichannel updates for control and waveform output applications such as stimulus-response tests, including acoustic distortion testing, and simulation such as three-phase power simulation. In addition, the device provides eight 5 V TTL/CMOS digital I/O lines; two 24-bit, 20 MHz counter/timers; and digital triggering and external clocking capabilities.

Supplier: 3B Scientific

Evacuated glass flask containing i.a. electron gun with directly heated tungsten wire cathode and a cylindrical anode. The electron gun emits a divergent electron beam, aimed at an Maltese cross of aluminum placed in the middle of the tube. The cross can be connected electrically. At the same time, light from the filament is also directed towards the cross, so that a comparison can be made between the shadows of different types that appear on the luminescent surface at the far end of the tube. Specifications.

Supplier: PHYWE

With a special addition, the analogue instrument can be turned into a digital instrument with simultaneous analogue display. In order to extend the measurement possibilities, there are also measurements for power and voltage amplification. The replaceable measuring areas are slid into a slot on the top of the instrument ('toaster principle').

Supplier: 3B Scientific

Highly evacuated electron tube with focusing electron gun and fluorescent screen (90×60 mm) inclined relative to the beam axis, so that the path of the beam can be seen and the effects of electric and magnetic fields can be studied. The electron beam can be deflected electrically in the electric field of the built-in plate capacitor, and magnetically by using an optional Helmholtz coil pair D. By adjusting the electric field so that it cancels the magnetic deflection, it is possible to determine the specific charge e/m and the velocity of the electrons.

Supplier: 3B Scientific

Tube holder to support all S series electron tubes for easy and safe operation. The five pin sockets for the tube are concealed inside the tube holder. A cathode protection switch is integrated into the tube holder, to protect the heated cathode from excessive voltage. The base plate has a slot for attaching the Helmholtz pair of coils S.

Supplier: 3B Scientific

Highly evacuated electron tube for determining the wavelength of electrons as a function of the anode voltage from the radii of the diffraction rings and the distance between the lattice planes of graphite (Debye-Scherrer-diffraction) and rendered visible on a fluorescent screen. Also intended for determining the wavelengths of monochromatic radiation at different anode voltages from the radii of the diffraction rings and the lattice plane spacing of graphite, as well as confirming de Broglie’s hypothesis.
