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.

Sintered Neodymium Countersunk Segment Magnet ADVANTAGES
Advantages and disadvantages of magnetic materials

They corrode quickly, unless they are coated, due to their iron content
They start to demagnetise at anything above 80°C

Nickel-copper-nickel coatings, (known as nickel coatings), consist of three different coats: nickel, a layer of copper, and then a second layer of nickel.
This type of coating can be painted over, which makes a nickel-copper-nickel coating more visually attractive than the other magnetic coatings available.
This method of painting the coating is used on bar magnets which need the different magnetic poles to be painted in different colours for educational purposes.
