CMS Magnetics Bar Magnets Grade N45 4x12x12 Inches 1 Ea_ Rare Earth Neodymium Magnetic Blocks

General Description These rare earth neodymium Bar magnets are made for holding stuff & that is what They do they do best. They are Grade N52 Magnetic Square These magnets come with teflon separators to both protect your magnets and make separating them easy. Neodymium magnets are unique because of their extreme resistance to demagnetization and will only lose their magnetism if they're heated above 176 degrees fahrenheit. Technical Magnets Each Of These Bar Magnets Provides 127 Pounds Of Holding Power Maximum Working Temperature 176 F (80 C) Material: Sintered Ndfeb Neodymium Rating: 14,400 Gauss Pulling Force Pole Orientation: Axially Magnetized, The Poles Are On The 1/2 " Thickness Coating: ni+Cu+Ni 3 Layer Plated Tolerance: All The Dimensions Are +/-0.002in With Coating These are not the Small Bar magnets you played with as children 15-20 times the force of those old time magnets. Never experienced powerful neodymium magnets? Now is the time! Our rare earth magnets have a high saturation magnetization & tetragonal crystalline structure ensuring top physical pulling force & maximum energy product. These magnets hold very well against steel surfaces with direct touch and direct pull. The magnetic strength will last forever under normal use. Many Uses & Users Cms magnetics neodymium Bar magnets are used by school teachers machinists magicians engineering and manufacturing students hobbyists inventors technicians diyers mars rovers (yup up there) craft magnets uses hobbies therapy storage experiments science fairs magnetic bars labs garages schools offices & refrigerator magnets
