Pronunciation: [dɪmˌaɡnɪta͡ɪzˈe͡ɪʃən] (IPA) 
The word "demagnetisation" is spelled with a stress on the second syllable "ma". It is pronounced "diːˌmæɡnətaɪˈzeɪʃən". The "d" at the beginning is pronounced softly and the "g" in the second syllable is pronounced like a "j" as in "gin". The word in English means to remove magnetism from an object. It is derived from the Greek word "magnēs" meaning magnet and the suffix "-ation" meaning a process or state.
Demagnetisation refers to the process of removing or reducing the magnetism of a material or object. It involves the reduction or elimination of the magnetic field that is naturally present in a magnetized material. This can be achieved through various techniques or processes.
One common method of demagnetisation involves subjecting the magnetized material to an alternating current (AC) or an alternating magnetic field. This would cause the magnetic domains within the material to oscillate and eventually randomize their alignment, canceling out the overall magnetism. Another technique may involve heating the magnetized material to its Curie temperature, which is the specific temperature at which the material loses its magnetism.
Demagnetisation is commonly employed when it becomes necessary to remove magnetic properties from certain objects or materials. This is particularly important in certain manufacturing processes or industries, such as electronics, where magnetism can interfere with the operation of electronic components or devices.
Overall, demagnetisation is the process by which magnetism is removed or reduced from a magnetized material or object, allowing it to become neutral or non-magnetic. Through various techniques, such as applying an alternating current or heating the material, the magnetism is disrupted and eliminated, ensuring the material is no longer magnetized.
The word "demagnetisation" is derived from two primary roots: "de-" and "magnetization".
1. "De-" is a prefix in English, derived from the Latin prefix "dē-", meaning "down", "away", or "from". It indicates reversal or undoing an action. In this case, it suggests reversing or undoing the process of magnetization.
2. "Magnetization" is the process of making an object magnetic or acquiring magnetic properties. It is formed by combining the noun "magnet" with the suffix "-ization", which indicates the process or result of.
Putting them together, "demagnetisation" refers to the process of removing or reversing the magnetization of an object.
