Switching From Ferrite Magnets to Rare Earth Magnets Switching from traditional ferrite magnets to rare earth magnets is no small thing. Magnets are measured by their BHmax score. The higher the number the stronger the magnet. Most traditional ferrite magnets will have a BHmax of no higher than 3.5. A rare earth magnet can have [...]
What Exactly Is A "Strong" Magnet? Aren't all magnets strong? What exactly makes a magnet "strong?" We reveal this ancient secret on our blog today. All magnets have a specific energy density that can be measured, and not surprisingly, some of these magnets have a greater strength than others. Take your everyday fridge magnet. These [...]
What is the Strongest Commercial Permanent Magnet in the World? The Strongest Permanent Magnet-Neodymium Magnets Neodymium Magnets At room temperature, the neodymium magnet is the most powerful permanent magnet. But this is only at room temperature. Early Neo magnets had an annoying flaw: they were sensitive to temperature, and when the temperature rose, the magnetism [...]
Magnet Concept Am area of the magnet, is the cross sectional areal of the magnet perpendicular to the central flux line, measured in sq.cm. at any point along its length. In design, am is usually considered the area at the neutral section of the magnet. B Magnet induction, is the magnetic field induced by a [...]
Bonded Magnets: A Versatile Class of Permanent Magnets Permanent magnets are ubiquitous in modern societies. Devices that use permanent magnets include motors, sensors, actuators and acoustic transducers. These are used in home appliances, speakers, office automation equipment, aerospace, wind turbine generators, medical laboratory diagnostic test equipment and more. It is estimated, for example, that a [...]
Choosing a Permanent Magnet Have 3 Key Parameters Choosing a Permanent Magnet - Every type of permanent magnet has a unique set of characteristics that can affect how is performs in various applications. When evaluating magnet options for your project, pay attention to the following: 1. Temperature One of the most important parameters to consider [...]
Magnets measured and graded for strength, quality, etc. here you can learn about it, thanks. Magnets measured and graded Magnet Strength Measurements (B)--The units for measuring the field strength (flux density) of a magnet are Gauss or Tesla. 1 Tesla = 10,000 Gauss. The Earth's magnetic field is on the order of 1 [...]
