  • +/-0.2mm manufacturers tolerance on any dimension
  • Magnetised through the thickness so that one 10.8mm x 6.3mm face is north and the other is south.
  • North pole is painted red
  • These magnets are all new, directly from the manufacturer, however, they have been cut from larger blocks and it is not unusual for the edges to have chips and nibbles or for there to be patches of discolouration. This does not affect the either the power or performance of the magnets.

Ferrite magnets are also known as ceramic magnets. Strontium (chemical symbol Sr) is element number 38 on the periodic table. This means it is an alkali earth metal. Ceramic magnets are manufactured by compressing an Iron Oxide and Strontium Oxide powder and then sintering at high temperatures. They have a wide range of applications due to their low cost and are available in a wide range of shapes.

It has excellent resistance to demagnetisation and operates at temperatures from -40C to +200C. It does not corrode even in salt water and has good chemical stability except in concentrated acid environments. It also has a high electrical resistance which is why it is used in loud speakers.

Their principle applications are in DC motors, loudspeakers, reed switch operation and general holding devices such as pot magnets. Unmagnetised shapes can be machined using diamond cutting machines.

These magnets are stronger than ordinary craft magnets and ideal for making for fridge magnets out of:

  • images
  • moulding clay
  • wood
  • plastic
  • metal bottle caps
  • and other craft and educational projects

WARNING: Adult supervision required - choking hazard. Do not allow these magnets to jump together or to an iron/steel surface - they will chip. THIS IS NOT A TOY. DO NOT INGEST

NOTE: a complete box contains 10010 magnets and we have a price break created to cater to this.
