What magnet is stronger than neodymium?

Hint: Neodymium is a rare earth metal having symbol \[Nd\]and atomic number 60 belonging to the Lanthanide series. The electronic configuration of neodymium is \[\left[ {Xe} \right]4{f^4}6{s^2}\]. \[\]

Complete Step by Step Solution:
Neodymium is the strongest permanent magnet found. A neodymium magnet is an alloy of iron, boron, and neodymium \[\left( {N{d_2}F{e_{14}}B} \right)\].
Neodymium magnets are strong as they are demagnetization resistant and they have a high level of saturation due to which they produce a strong magnetic field.
Iron nitride magnet is stronger than neodymium and is made up of iron and nitrogen having chemical formula \[F{e_{16}}{N_2}\]. As the cost of iron and nitrogen is very low and of which iron nitride is less expensive than neodymium. Thus, making it an economically friendly magnet.

It is a very environmentally-friendly magnet. It is used in the manufacturing of many appliances like electric motors, electronics, and turbines. It is an alternative to rare earth metals. Iron nitride magnets do not have any limitations yet and are thus preferred over neodymium.

Additional information: Magnetism is a force that is influenced by a strong magnetic field. A strong magnet is strongly attracted to the magnetic field. Magnetism may be caused by the electron spins which create a dipole moment. The elements which have unpaired spins, their small magnetic field somewhere become large because of this a strong magnetic field produced around metal and it may behave as a magnet.

Note: There are three types of magnets that are temporary, permanent, and electromagnet. Neodymium is a permanent magnet.
