The bigger the air gap, the bigger the reduction in the magnet\u2019s performance and pull.<\/p>\n\n\n\n<p>Air gaps affect the magnetic circuit that a magnet produces, breaking these circuits and subsequently forcing the magnetism to \u2018jump\u2019 from the magnet to the other object to continue the circuit.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>How Does Air Gap Affect Magnet Selection?<\/strong><\/h2>\n\n\n\n<p>If there is a potential or certain air gap in your application, it\u2019s important to select a magnet with greater strength in order to compensate for the magnetic strength being lost as a result of the air gap.<\/p>\n\n\n\n<p>For example, by mounting a magnetic hook to a wall in an office or home, the magnetic field must travel through numerous non-magnetic materials in order to reach the stud within the wall it is attracting to. This application has a large air gap present.<\/p>\n\n\n\n<p>Whereas if you were to hang a magnetic hook directly to a ferrous surface in a warehouse or garage, there will not be very much of an air gap present at all, aside from the actual air. Meaning you can use a magnet with less strength.<\/p>\n\n\n\n<p>If an air gap is not taken into consideration when choosing a magnet for your application, you may not be able to select the correct magnet for your application.<\/p>\n\n\n\n<p>If you are unsure about what magnet would best suit your application be sure to get in touch with our experts today on 0845 519 4701 or email
