Mounting bench, Risø sources
Mounting bench, Risø sourcesComplete mounting bench for Risø sources*) and GM tubes, which provides a stable platform for experiments with radioactivity.
Multichannel analyser
Multichannel analyserA multichannel analyser (MCA) sorts incoming pulses from an energy-sensitive detector into a large number of channels according to size.
Multimeter
MultimeterThis multimeter is suitable as a student model. It has measurement areas within; Direct and alternating voltage, direct current, resistance values, transistor test and diode test.
Mysterious spinning top
Mysterious spinning topGive this spinning top a spin and watch it spin for hours without stopping.
The secret revealed: the spinning top contains a small magnet. As this magnet moves past the center of the black base, the top’s magnetic field induces a current in a coil, which closes a switch, allowing a battery to instantly activate a small electromagnet. The spinning top increases its speed and spins away from the center of the base.
Nature viewer with 2x and 4x magnif.
Nature viewer with 2x and 4x magnif.Versatile magnifier with two magnifications: 2x and 4x. A grid is printed at the bottom as a reference.
Neodymium magnets Ø12 mm
Neodymium magnets Ø12 mmThe neodymium magnets have a diameter of 12 mm, a height of 4 mm and a weight of 3.4 g. They are of the N45 type, which means that they are very powerful in relation to their size. The magnets are made of neodymium, which is known for its high strength and stability, and they can therefore hold a considerable weight despite their compact shape.
Neodymium magnets, Ø 10 x 8 mm
Neodymium magnets, Ø 10 x 8 mmThese magnets are so powerful that they can even demonstrate the properties of extremely weakly magnetic materials.
