Neodymium (Nd-Fe-B) magnets, known as neo magnets, are common rare earth magnets composed of neodymium (Nd), iron (Fe), boron (B), and transition metals.
The two processes used to manufacture neodymium magnets are sintering and bonding.
Neodymium magnets have become the most widely used of the many varieties of magnets.
The magnetic field of a neodymium magnet occurs when a magnetic field is applied to it and the atomic dipoles align, which is the magnetic hysteresis loop.
Neodymium magnets can be produced in any size but retain their initial magnetic strength.
