Simply, the higher the maximum energy product value, the greater the magnetic field the magnet will generate in particular applications.&nbsp;<\/p>\n\n\n\n<p>A magnet of grade N42 has a Maximum Energy Product of Gauss 42 MGOe, while an N52, at 52 MGOe would be incrementally stronger.&nbsp;<\/p>\n\n\n\n<p>Typically, higher grades should be used when the highest performance is needed and the available space for a magnet cannot be increased, otherwise, it may be more beneficial to use two N42 magnets compared to using one N52 magnet.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter

have a different maximum operating temperature.<\/p>\n\n\n\n<p>The maximum operating temperature is the maximum temperature a magnet can withstand before it begins to lose its magnetism permanently, these ratings should always be treated as a guide value as other factors such as shape and size will also affect the performance of a magnet at high temperatures.<\/p>\n\n\n\n<p>You can view the <a
