20mm Dia x 10mm N52 Neodymium Strongest Grade Magnet Description: Strong magnetic NdFeB Circular Disc Magnets are made from Neo Neodymium Magnet material and have strong magnetic performances. Super strong Rare-Earth magnets – once they get stuck with each other, they are hard to break apart. You should be careful to break apart not use strong power to pry open or it would cause damage and cracks in the magnetic material. Features: Shape: Disc Grade: N52 Plating: Ni-Cu-Ni ( Nickel ) Max Temp (degrees C): 80 Material: NdFeB Color: Silver Magnetic face diameter: 20mm Thickness: 10mm Quantity: 1 pcs Applications: Acoustic field: the speaker, receiver, microphone, alarm, stage audio, car audio and so on. Electronics: permanent magnetic actuator vacuum circuit breakers, magnetic relays, meter, meter, sound meter, a reed switch, sensors. Electrical field: VCM, CD / DVD-ROM, generators, motors, servo motors, micro-motors, motors, vibration motors. Machinery and equipment: magnetic separation, magnetic crane, magnetic machinery. Healthcare: MRI scanners, medical equipment, magnetic health products and so on. Other industries: magnetized Wax, pipe descaling, magnetic fixture, automatic mahjong machine, magnetic locks, doors and windows magnetic, magnetic luggage, leather magnetic toys, magnetic tools, gifts and packaging. Tip: 1, Strong magnets should Keep away from Ironware and some easily magnetized iron products, such as monitors, bank cards, computers, televisions, mobile phones and other 2, Strong magnets should be stored in a dry, heated environment, and need to use of plastic, wood, cardboard, foam to separated and wrapped. 3, Magnets might be interested in water meter ,Electric meter, gas meter and some metering equipment exist some inaccurate affect (Such as : if magnets placed near the meter, the meter will slow down) Note: Be careful fragile and clip hand, placed in a dry place, stored at room temperature. WARNING: This is a seriously powerful magnet and it is totally unsuitable for children… Package Included: 1 x Strong magnetic NdFeB
Three surplus ceramic ring magnets are slid onto a vertical PVC pipe. WHY DO THEY FLOAT?!
The pipe is then mounted horizontally. Paper clips and a steel rod readily stick to them, but the magnets repel each other – until the end when one is reversed.
All magnets have a north seeking pole and a south seeking pole. Like poles (North|North or South|South) repel. Opposite poles (North|South) attract.
Experimenting with a wind generator? The principle of “Floating Magnets” can be used to create a magnetic bearing.
