&lt;p&gt;Neodymium magnets are widely used in geocaching to attach magnetic geocaches. They are small and very powerful. Disadvantage of neodymium magnets is weak resistance to high temperature. They begin to lose magnetic power when +80°C temperature is reached - it is important to know, when attaching magnets to containers using glue guns and thermo tubes. Opposite to neodymium magnets, there are ferrite magnets which resistance to high temperature is up to +300°C. Another disadvantage of&amp;nbsp;neodymium magnets - they are expensive.&lt;br /&gt;
Oblong for of the magnet is convenient&amp;nbsp;to attach it to the 35 mm photo film canister or PET preform.&lt;/p&gt;
