Huge inventory | Low prices | Fast shipping

Neodymium Disc and Cylinder Magnets - are the strongest disc and cylinder magnets on the market and are classified as permanent rare-earth magnets. Our neodymium disc magnet and cylinder magnet selection features - fridge magnets, plastic and rubber coated magnets, adhesive backed magnets, sewing magnets, etc. in standard and some metric sizes from super thin flat disc magnets to tall and thick cylinder magnets. If you need a size or grade we do not stock, we provide Custom Disc & Cylinder Neodymium Magnets in addition to full service expert magnet engineering and design advice, abundant free knowledge and DIY guides and free magnet strength and field calculators.

Types of disc and cylinder magnets

Disc magnets and cylinder magnets are wide terms and also know as many other names such as round or circular magnets or rod magnets. Our disc and cylinder magnets are mainly divided into these 3 distinct categories.

Disc Magnets

Disc magnets where thickness is less than diameter
Cylinder Magnets

Cylinder magnets where thickness is greater than or equal to diameter
Diametric Disc & Cylinder Magnets

Disc and cylinder magnets with diametric magnetization

Available coatings for disc and cylinder magnets

We provide the below nickel (Ni-Cu-Ni), black nickel (Ni-Cu-Ni-BlackNi), gold (Ni-Cu-Ni + Au), rubber and plastic coatings for our disc and cylinder magnets. Our default coating is a 3-layer nickel-copper-nickel (Ni-Cu-Ni) to protect from moisture and corrosion, enhance durability and to give a nice smooth silver finish. Additional coatings such as epoxy (Ni-Cu-Ni + epoxy) and silver (Ni-Cu-Ni + Ag) available. See custom neodymium disc and cylinder magnets for more details

Disc and cylinder magnet magnetization directions

We offer disc and cylinder magnets in through thickness and diametric magnetization directions. Most of our disc and cylinder magnets are axially magnetized through their thickness and the rest are diametrically magnetized across the diameter of the magnet. Our disc and cylinder dimensions are listed in order of diameter then thickness. Below are diagrams of two magnetic polarizations we provide.

Magnet FAQ

Answers to many common and uncommon magnet questions

What is a disc magnet or cylinder magnet? - A disc magnet is basically a circle with a thickness. A cylinder magnet will tend to have a thickness greater than the diameter of the circle, but there is no clear distinction between the two. Disc magnets are also known as round, circular/circle, button, or wafer magnets and cylinder magnets are also known as rod, tube, barrel or cylindrical magnets.

What are disc and cylinder magnets used for? - Disc magnets and cylinder magnets seem to be the most popular magnet shape and are used for a wide variety of different applications in industrial, commercial, consumer electronics and other products, craft, hobby, DIY, hanging things and more!
