How do you measure the pull strength of your magnets? Do you have a minimum purchase order?ĭepending on approved credit there is a $100.00 minimum for purchase orders, however if an order is prepaid via credit card or check there is no minimum order.Ģ0. No, once a magnet has been fully magnetized it can’t be made stronger.ġ9. Can I increase the strength of my magnet? All our magnets have the gauss listed in the description box of each product.ġ8. The gauss varies depending on the size of magnet. You can call us or find details on our Custom Magnets Page. We serve the US and most international markets. Yes, we have the capability to produce magnets to your specification in NdFeB, SmCo, AlNiCo, Ferrite, and rubberized magnet materials. Yes, when two or more magnets are stacked together they become stronger, however they will not be proportionally stronger all the time due to the nature of the material. Will stacking my magnets together make them stronger? No, we are unable to produce monopole magnets at this time in NdFeB.ġ5. Neodymium magnets are the strongest magnets in the world.
The only way you could cause damage is if you place a strong neodymium magnet directly on your hard drive.ġ3. Hard drives already contain a powerful neodymium magnet, so having another magnet by your computer won’t affect your data. Magnets can damage magnetic tape storage media and floppy disks, so you will want to keep magnets away from these devises. No, you wouldn’t want to place a magnet directly on your hard drive or computer case, having them nearby though will not harm your computer. Will magnets harm my computer or erase my hard drive? No, magnets will not damage these appliances.ġ1. Can I damage my refrigerator, stove, oven, or microwave if I put magnets on them? For small electronics like cell phones, iPods, calculators and other devices that don’t contain magnetic storage there shouldn’t be any problems, but just to be on the safe side try to avoid close contact with neodymium magnets.ġ0. They can also cause damage to TV’s, computer monitors and other CRT displays. They can… The strong magnetic field of neodymium magnets can damage certain magnetic media such as credit cards, magnetic I.D. Strong magnets can cause physical harm if not handled properly, please view our Neodymium Magnet Safety page for complete details. There are currently no scientific studies that prove this however. Some people actually believe magnets can have health benefits and help the healing process. There can be issues if the person has a pacemaker, so you should consult your doctor for information on this. There are no known health risks caused by being exposed to neodymium magnets.
Are there any health or safety risks with neodymium magnets?
You will not even notice unless you measure it.Ĩ. As long as you don’t over heat them they will lose less than 1% of their strength every 10 years. Neodymium magnets are the most permanent magnets in the world. Do neodymium magnets lose their strength over time? Most of our magnets are nickel plated but we do stock some sizes in gold and epoxy plating. If a longer time is required Epoxy plating is recommended. Salt water is not good for NdFeB magnets as the Ni plating will corrode rapidly (24-48 hrs). How long does the plating last when used in salt water? Most of our magnets are grade N40 so if they are heated above 80˚C or 176˚F they will demagnetize and lose their strength. We can produce custom magnets that withstand high temperatures. Depending on the grade of the magnet, the heat will demagnetize the magnet. Do I need to worry about temperature with neodymium magnets? The high heat will demagnetize the magnets and the magnets could catch fire.ĥ. See After Market Machining for more details.Ĥ. Heat produced by machining can quickly demagnetize the magnet. Neodymium magnets are very hard and brittle and any kind of machining can break or damage the magnet. Can I cut, drill, or machine neodymium magnets? Machining magnets can be a tricky process and we do not recommend it unless there is no other option. The higher the number the stronger the magnet is, however the higher the number the more brittle the magnet becomes as well. Neodymium magnets are graded by the maximum strength they can be magnetized to. Neodymium magnets are the strongest rare earth magnets and the strongest magnets in the world.Ģ. Rare earth magnets are made from rare earth elements found on the periodic table. Neodymium magnets are the most commonly used type of rare earth magnets. Are neodymium and rare earth magnets the same thing?
