Neodymium iron boron (NdFeB)
Neodymium magnet elements: Neodymium Nd, Iron Fe, and Boron B
Neodymium magnets are made up of an alloy containing neodymium, iron, and boron.
They are the most common type of magnet available as they can produce the strongest magnetic field in a very small area due to the materials that make up the magnet being a stronger combination than any other.
Due to the magnetic force they produce, neodymium magnets can be used for any type of magnet from magnetic sweepers to magnetic discs.
ADVANTAGES
Advantages and disadvantages of magnetic materials
DISADVANTAGES
They corrode quickly, unless they are coated, due to their iron content
They start to demagnetise at anything above 80°C
