5 ALNICO MAJOR MAGNET This is the original Major magnet, from a UK supplier, and is an extremely powerful but precision permanent magnet assembly. The Alnico Major Magnet comprises a large, very sturdy C-shaped alnico magnet (Aluminium/Nickle/Cobalt) with high quality ferromagnetic (steel) poles. The assembly is precisely magnetised and adjusted to give a 2000 Gauss field reading in the air gap between the steel poles (equivalent to 2 kG, 200 mT or 0.2 Tesla). The Alnico magnetic material has excellent thermal characteristics, with a maximum operating temperature of 550 degrees C and good corrosion resistance. The pole/air gap between the steel poles is 27.3 mm, which makes it suitable for use in applications which require a magnetic field strength of known value in an air gap . Typical applications in industry include mass spectrometry, medical experiments, sensor designs, and generator experiments whilst in education it can be used for flux density measurements, eddy current dampening, Fleming’s (Pohl’s) swing, magnetising ferromagnetic materials, deflecting electron beams and demonstration of moving coil meters. Supplied with magnet keeper. Dimensions: 111 mm high x 103.5 mm wide x 50 mm thick Weight: 2.9 kg Cat No. Description Price Per MAG-560-100 Alnico Major Magnet 364.44 ea. 6 FLOATING MAGNETS - SMALL A set of 5 colour plastic encased ring magnets with a plastic stand to create a floating magnet trick. Children achieve this simply by stacking the rings with like poles facing each other so that they repel. Size: Height 123mm x Dia. 42mm. Cat No. Description Price Per MPR-050-100 Floating Magnet - 5 Small 5.98 set 7 SUPER MAGNETS - NEODYMIUM Feel the ultimate pulling power of magnetism with these Super Magnets. Housed in tough colour coded outer mouldings (red - North, blue - South) the design allows children to safely experience first hand the force of neodymium - currently the world’s strongest permanent magnet!
