Also, when trying to determine or measure a magnets strength the answer will be dependent on what is meant by strength be it either the pulling force or magnetic field strength, which are both often referred to as strength. So below we will describe each attribute that contributes to a magnets performance and in turn answer the question how is the strength... Read More

Handling Magnets Safely

Magnets can be extremely useful and have many benefits for a wide range of applications, but they do come with some hazards. If you place two magnets close to each other you will see them attract, in which they leap towards each other with great acceleration and then slam together. All our magnets are tested, and each magnet is clearly labelled with its pull-strength and our stronger magnets are packaged alongside a warning brochure. Neodymium magnets are amongst the strongest magnets in the world, and the force at which they... Read More
