The word "magnetisation" is spelled with the letter "s" instead of a "z" at the end, despite the pronunciation of the "s" sounding like a "z" sound. This is because of British English's preference for using "-ise" endings instead of "-ize" endings. The IPA phonetic transcription for "magnetisation" is /ˌmæɡnɪtaɪˈzeɪʃən/. Despite the spelling difference, the word means the same thing and refers to the process of magnetizing an object or material.
Magnetisation is the process by which a material, such as iron or steel, becomes magnetized or acquires magnetic properties. It involves aligning the individual magnetic domains within the material so that they all point in the same direction, creating a net magnetic field. This alignment can occur spontaneously in certain materials, known as ferromagnetic materials, or it can be induced by an external magnetic field.
The magnetisation of a material can be achieved through various methods, including exposure to a magnetic field, rubbing it with a magnet, or passing an electric current through it. These processes cause the magnetic domains within the material to rearrange and align, resulting in an overall magnetization.
Magnetisation is a fundamental property of magnets, and it is responsible for their attractive or repulsive behavior when interacting with other magnetic or magnetizable objects. The strength of magnetisation is typically measured using units such as magnetic flux density (tesla) or magnetic induction (webers per square meter).
Furthermore, magnetisation plays a crucial role in many technological applications, such as electric motors, generators, transformers, magnetic storage devices (like hard drives or magnetic tapes), and magnetic resonance imaging (MRI) machines. Understanding the principles of magnetisation is important in these fields to harness the properties of magnets effectively and develop efficient and reliable devices.
The bringing into a magnetic condition; the state of the object so brought.

The word "magnetisation" derives from the noun "magnetize" combined with the suffix "-ation".
The noun "magnetize" comes from the word "magnet", which originated from the Latin "magnes" or "magnesia", referring to a type of rock found in Magnesia, a region in Ancient Greece. The rock was known to have a natural magnetic property, leading to the development of the word "magnet" to describe objects with magnetic qualities.
The suffix "-ation" is derived from the Latin suffix "-atio", which signifies the action or process of a verb. Adding this suffix to "magnetize" forms the noun "magnetization", which refers to the action or process of making something magnetic or the state of being magnetized.
