Choosing the best magnet shape
We are proud of the diverse and extensive range of magnets we have available and you can purchase all of our magnets online. However we understand it can be overwhelming to choose the best magnet when there are so many to choose from. We have put together a number of helpful articles in our FAQ and Knowledge Base page to assist our customers. Our friendly sales team are always happy to help if you have any questions and you can contact them via email, phone or via our contact form.
One of the many things to consider when buying a magnet online for your project is the shape of the magnet. Each shape has qualities that make it well suited to different applications, environments or circumstances.
Disc magnets are one of the most widely used shapes. They are ubiquitous in large part due to their appealing thin profile. They are able to be slotted into small spaces or thin materials without compromising the overall look and feel of the product. Ring magnets are also used for this type of application as well as for a number of mechanical situations. The hole in the centre of the ring magnet provides an easy point of attachment, enabling it to be slotted onto other objects we ease.
Cylinder magnets provide increased magnetic power compared to a disc of the same diameter. This is due to the increase in magnetic material present. Cylinder magnets produce a deep and concentrated magnetic field. They are a great choice for applications where the space on one plane or aspect is limited.
