Measurements
Temperature resistance
Ferrite magnets can be used at temperatures between -40 °C and 250 °C, while most neodymium magnets lose their magnetisation permanently at a temperature of 80 °C. However, temperatures under -40 °C are no problem for neodymium magnets.
Outdoor use
Ferrite magnets are very chemical and rust resistant, while neodymium magnets are not suitable for outdoor use.
Brittleness
Ferrite magnets can break into pieces when you repeatedly put a strain on them. Neodymium magnets are very brittle and crack easily, which can lead to injuries of user or bystanders.
