These hold very well against steel surfaces with direct touch and direct pull. The magnetic strength will last forever under normal use.

Many Uses & Users For A Ring Magnet 

Cms magnetics’ super strong neodymium ring 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 & as a strong earth magnet

These powerful ring magnets neodymium are comprised of strong neodymium material makes them the strongest ring magnets of their size commercially available. These Ring magnets are axially magnetized so the north and south poles are on the flat surfaces, and the red line on one side of the ring magnet denotes which side the north pole is on. Neodymium ring magnets are strong magnets & are unique because of their extreme resistance to demagnetization.  These ring magnets  will only lose their magnetism if they're heated above 176 degrees Fahrenheit.  Our Strong Neodymium Ring Magnets have a special set of uses in the world of magnets. Ring magnets are specially suited to those magnetic repulsion experiments where you dangle 2 magnets from a string, but also Jewelry and in the medical field.  One magician we know even wanted one that looks like a wedding ring.  Hmmm, the methodology for the trick would be hiding in plain site. 

 About Neodymium in General

Neodymium magnets overall, are the world's strongest permanent magnets. Although, not all neodymium Ring magnets share the same characteristics. The Grade of a Neodymium Magnet will provide an idea of the strength of a neodymium magnet. The most common commercially available grades generally run N35- N52.  N35 is the weakest (but by no means weak) and N52 is currently the strongest. There are some special use grades as well. A larger piece of neodymium of a weaker grade may be ultimately stronger than a smaller but higher grade piece. Our strong Ring magnets are designed & manufactured to meet stringent quality standards of both external and our own standards. 

Neodymium Magnets are the popular  choice for Homes, Work, Shops, DIY, Science, Hobby, Crafts, Office, Fridge, Science, Fair, Just Plain Fun, Alternative, medicine, Sorting metal items, Hold things up, Hold, things, down, Duvet, Cover, Closures, Hanging, Art, scarves, jewelry, belts, Handbags & Classroom Decorations.   

Ring Magnets, Magnetics & Magnetism

This article will discuss the world of magnets from very different end users viewpoints.  Firstly the article is addressed to someone in a high school or maybe a 101 level in college to aid them in navigating this part of physics.  This portion of the article will also point to experiments that will demonstrate the points being made.  

Secondly this post will address the “what does that mean to me?” group.  Usually consumers of magnets whether they are a hobbyist searching for a small magnet to hand a photograph, an organizer searching for a way to straighten up a workshop or a manufacturer in search of enough magnets quickly to finish a current run on a manufactured product. 

Magnets This article is about objects, materials, devices that produce magnetic fields. Most of the subject matter here covers all Neodymium Ring Magnets  . We will in many cases be using the term “Neodymium Ring Magnets” as the example, as this is the title & subject matter of this particular category. 

The information given applies not only to the Neodymium Ring Magnets  but the composition of all Neodymium Magnets .

Neodymium Ring Magnets are made of neodymium, an iron alloy. The Ring magnet, made in the shape of a Ring, the 2 magnetic poles in this case are through the thickness. This shape of a magnet make it very useful in both industry and by the casual consumer.  The Ring Magnet’s shape is one of the major divisions of magnets. The Ring Magnet needs to physically fit where the consumer needs it to fit. Neodymium is a magnetic material that was applied to magnets in the 1980s. Neodymium is the strongest Ring Magnet   in the world. Actually the material is the strongest permanent Ring Magnet in the world. The term “permanent” is just saying that you cannot turn it off & on at will as in an electromagnet.  

Neodymium Ring MAGNET

Magnetic field lines of a Neodymium Ring Magnet   as illustrated below with the iron filings.

Here is a short video showing an easy experiment performed with a neodymium cube magnets and some iron filings that will demonstrate the magnetic field produced by this product.

The magnetic field can also be seen with a piece of  Magnetic View Film Green 4x6".

The magnetic field can be said to be its area of influence.  As you can see this Influence (strength) drops off sharply when moving away from the magnet.

Ferromagnetic materials can be divided into magnetically "soft" materials like annealed iron, which can be magnetized but do not tend to stay magnetized, and magnetically "hard" materials, which do. Permanent magnets are made from "hard" ferromagnetic materials such as alnico and ferrite that are subjected to special processing in a strong magnetic field during manufacture, to align their internal microcrystalline structure, making them very hard to demagnetize. To demagnetize a saturated magnet, a certain magnetic field must be applied, and this threshold depends on coercivity of the respective material. "Hard" materials have high coercivity, whereas "soft" materials have low coercivity. The overall strength of a magnet is measured by its magnetic moment or, alternatively, the total magnetic flux it produces. The local strength of magnetism in a material is measured by its magnetization.

An electromagnet is made from a coil of wire that acts as a magnet when an electric current passes through it but stops being a sphere magnet when the current stops. Often, the coil is wrapped around a core of "soft" ferromagnetic material such as mild steel, which greatly enhances the magnetic field produced by the coil.

A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials, such as iron, and attracts or repels other magnets.

A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on the refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include the elements iron, nickel and cobalt and their alloys, some alloys of rare-earth metals, and some naturally occurring minerals such as lodestone. Although ferromagnetic (and ferrimagnetic) materials are the only ones attracted to a magnet strongly enough to be commonly considered magnetic, all other substances respond weakly to a magnetic field, by one of several other types of magnetism.
