A device used to evaluate the strength of a magnetic field, specifically the force required to detach a magnet from a ferrous surface. These kits typically include a calibrated scale or gauge attached to a mechanism for applying increasing force until separation occurs. An example would be measuring the holding power of a magnetic base for a drill press or verifying the adhesion of magnetic lifters used in industrial settings.
These assessments are vital for ensuring safety and reliability in various applications. They provide a quantifiable measure of magnetic performance, offering confidence in equipment functionality. Historically, estimations of magnetic strength relied on subjective observations. However, standardized test methods have evolved, enhancing accuracy and allowing for consistent comparisons across different magnets and applications.
