These versatile high-performance ring magnets, with north and south poles on opposing circular faces, have many uses. They are used in many everyday appliances such as vacuum cleaners plus motors, generators, rotor shafts and more. They can even be used to demonstrate intriguing 'eddy currents' using a 9mm copper pipe. Simply slide the ring over the pipe and let it slide down its length and watch it slowly descend as the eddy currents produced create a damping effect. A great way to bring magnets to life in the classroom. PERFECT FOR ENGINEERING & MANUFACTURING. They also have many uses in engineering and manufacturing where small size and maximum strength are required. CORROSION-RESISTANT PREMIUM COATING. Coated with three layers of nickel, copper, and nickel to reduce corrosion and provide a smooth and clean finish. RESISTANT TO DEMAGNETISATION. Excellent resistance to demagnetisation. STRONG MAGNETIC HOLD. Each magnet can support a steel weight of up to 8.1kg vertically from the magnetic face when in flush contact with a mild steel surface. SPECIFICATIONS. 19.1mm outer diameter x 9.5mm inner diameter x 6.4mm thick.
