Answer:
The strength of a magnet is determined by various factors such as the material used, shape and size of the magnet, distance between the magnet and the object it attracts, temperature, and external magnetic fields. The type of material used greatly affects its strength, with materials like neodymium and samarium cobalt being some of the strongest magnets available. Shape and size of the magnet also play a role, with larger magnets having greater strength. The distance between the magnet and the object it attracts affects the strength of attraction, as does temperature. External magnetic fields can also weaken a magnet's strength by altering its alignment.
