How Do Air Gaps Affect Magnets?
When it comes to considering factors that can reduce the performance of a magnet it is important to consider air gaps.

Understanding the difference between ferrous and non-ferrous metals is important.
It is possible for the very small components of mechanical wristwatches to become magnetised when placed in close proximity to very strong magnetic fields.
Gauss is a measure of magnetic induction and a value of density. A magnet’s Gauss measurement represents the number of magnetic field lines per square cm.
Coercive field strength is the measurement of a ferromagnetic material’s ability to withstand an external magnetic field without becoming demagnetised.
There are several grades of neodymium available ranging from N35 to N55 alongside high-temperature variations, but these letters and numbers can be confusing.
A permanent magnet if kept and used in optimum working conditions will keep its magnetism for years. Neodymium magnets only lose 5% of their magnetism every 100 years.
Magnets should not be drilled as they are brittle and are likely to break during the drilling process.
Neodymium magnets are hard making them prone to breaking and chipping which is why to protect our neodymium magnets we coat them with a nickel-coat-nickel.
The difference between magnets attracting and magnets repelling is very small, however, the attraction between magnets is slightly stronger than the repulsion.
