Shielding a magnet or attempting to block a magnetic field is a subject that several of our customers approach our experts with on a regular basis, so we decided to examine what materials can be used to shield a magnet. Before learning how to shield a magnet it’s important to know that magnetic shielding does not block a magnetic field. No material can stop the lines of flux from travelling from a magnet’s north to its south pole. However, it can be redirected. The simplest example of this would be... Read More

The Earth produces its own magnetic field, which emanates from its magnetic inner iron core. On the Earth’s surface the magnetic field is extremely weak compared to the permanent magnets used in many every day appliances. At the magnetic poles the Earth’s magnetic field is approximately 0.7 Gauss compared to the Gauss value of a relatively small 10mm diameter x 5mm thick N42 neodymium magnet which can reach 5100 Gauss. It is this magnetic field that makes a compass point north but for many species, the Earth’s magnetic field has... Read More
