Each piece is triple plated with Ni-Cu-Ni to prevent corrosion and rust. This ring magnet is made from joining six Arc shaped magnets. These pieces were custom made and magnetized in such a way to create an alternating magnetic field pattern. The first picture in the listing shows the magnetic pole arrangement once the Arc segments are joined together. Note: (The magnetic poles will not be marked on the pieces that you receive.) This design and magnetic pole arrangement resembles the Star of David pattern, often used for magnetic healing applications. This ring assembly is also a great choice for motor designs and experiments dealing with alternating magnetic fields. Please see pictures for further description and ask all questions before purchasing. Approximate pulling force: 45 lbs Approximate Dimensions: (Assembled Ring) 4″ O.D. 2″ I.D. 1/8″ Thick Magnetized through the thickness, meaning the poles are located on the large flat surfaces. This Sale Includes: Six Arc segments that will require assembly to make the 4″ Ring. These are not toys and should be handled with caution! Be careful during the assembly process. Allowing the magnets to snap together to hard will cause them to break or chip. Visit our Ebay store if you are looking for magnets or magnetic equipment.

Below is a short introductory video for Neodymium magnets as it relates to safety, selection and basic material information. Following the link is additional Magnet-House policy information and answers to some of our most commonly asked questions. Buyer’s Guide: Your first neodymium magnet Material Safety and Best Practices: All buyers should be aware that magnets have the potential to damage electronic equipment, display screens, other valuable items and life saving devices such as pacemakers. Neodymium and other Rare Earth magnets are very strong and present pinch hazards. Larger pieces of this material have the potential to break bones while smaller sizes present a risk for ingestion. This material should not be left unattended, in areas where pets or people under the age of 18 have access. Do not drill, cut or sand Neodymium Rare Earth material. These processes can expel dust particles and chemicals which are hazardous if inhaled. Hard impacts to this material will cause them to chip or break, creating projectiles and/or cut hazards. Hard impacts can also create sparks that pose a risk to flammable or ignitable materials. Appropriate personal protective equipment and other safety gear should be used at all times while handling magnets. Each of the safety topics and hazards mentioned here do not provide all of the risk associated with this material. All buyers for any of our magnetic material is responsible for making sure they are independently informed and understand all potential hazards before making a purchase. Each buyer accepts responsibility for any and all damages related to people and property at the point of purchase.

Should you have any questions related to one of our listings, please send us a message prior to making the purchase. Magnetic Material Information: While Neodymium Rare Earth Magnets are the strongest in the world, they are brittle by nature and require careful handling to prevent damage. This brittleness is true for all Neodymium Rare Earth Magnets. Any chips, cracks or breaks sustained to the material is solely due to mishandling of the product and has nothing to do with product quality or defective material. A Neodymium Rare Earth Magnet that is never handled, will never break but one that is not handled correctly will always break. Please handle with extreme caution! Allowing these magnets to snap together quickly or against a ferrous object to hard will cause them to chip or break. Super-strong neodymium magnets smashing and exploding As a general rule, the larger the magnet, the more susceptible they are to become damage. This is because they typically have higher pull force values and greater mass, which causes them to contact surfaces at a faster rate of speed and with greater force. Understand that smaller Neodymium Rare Earth Magnets also have the potential to become damaged from hard impacts. It is extremely important that each buyer understands how to properly handle this type of magnetic material before purchasing in order to prevent damage to the product. Any damage to the material after it is received and handled will not be covered under our 30-day return policy. This includes damage sustained to the item while trying to separate the material after receipt. If you suspect the item has been damaged in transit, it is important that you contact us prior to opening the package. Damage reported to us after the item has been opened will be deemed mishandling of the product by the buyer and is not eligible for a return, refund or exchange. All Pull Force ratings provided within each listing for our magnetic materials is based solely on calculations derived from various factors such as magnet dimensions, grade, plating type, surface conditions, etc.. The values provided are approximations and each individual magnet could potentially vary slightly from the estimate. We do however make every effort to provide the most accurate information to our customers. All buyers should understand that Pull Force values are determined based on applying the entire magnetic material face to a one Inch thick steel plate having perfect surface conditions. Using a magnet on material with poor surface conditions, applying the magnet to a ferrous surface having less than a one inch thickness or partial magnetic face contact will result is lower Pull Force values than what is stated in the listing. Additionally, all magnetic material will need to have direct contact to the ferrous surface in order to exert the total Pull Force capacity. We would also like to inform all potential buyers that Pull Force is not the same thing as Lift Capacity. For the most part, all Neodymium Rare Earth Magnets are rated in Pull Force. That value however does not directly translate to a magnets’ physical lifting capacity. There are currently no conversion tables available that provide this information. However in our experience, we have found this value to be around 30% of the rated Pull Force value. Meaning, a magnet with a Pull Force rating of 30lbs can approximately lift a 10lb object, assuming perfect conditions are present that maximize the magnetic material properties. Again, these values and estimates are not guarantees. All buyers should perform their own testing to validate all functionality regarding each specific application and end use before implementation of the material. Our intent here is only to provide general reference for customers unfamiliar with magnetic materials. Please also keep in mind that air gaps between the magnet face and ferrous material will greatly reduce Pull Force and Lift Capacity values. Air gaps include physical air as well as any other non-ferrous material. As an estimate, buyers can expect a loss of Pull Force and Lift Capacity at a rate of 50% per .125″ inch gap present between the magnet and ferrous material. Meaning, a magnet that has been proven capable to lift an object weighing 4lbs will only be able to lift an object weighing 2lbs when a single .125″ inch piece of wood is between the magnet and ferrous material being lifting. Again, we do not guarantee these values and they are being provided solely as a basis for understanding of how magnetic material functions.
