What does magnetiser mean?
A magnetiser is a device, tool, or person that gives an object magnetic properties. It is most often encountered in industrial or workshop settings, where a magnetic field is used to align the domains within a material such as iron or steel, allowing it to attract other magnetic objects. An electromagnetic magnetiser can create a strong, controllable field and may be used in manufacturing, metalworking, or the preparation of components that will later be magnetised. The word can also refer more generally to a mechanism or person responsible for magnetizing something. In British English, magnetiser is the standard spelling; North American English generally uses magnetizer. It is relatively uncommon in everyday speech but useful when discussing magnets, magnetism, or specialised equipment.
A device or tool used to give magnetic properties to an object.
"The technician adjusted the magnetiser until the component firmly held the metal shavings."
Especially used for tools and equipment in industrial or workshop contexts.
A person or mechanism that magnetizes something.
"The magnetiser is activated whenever the conveyor carries a new batch of components."
This is a less common and more general sense.
The plural is used when referring to multiple devices, tools, people, or mechanisms.

A magnetiser can turn an ordinary piece of steel into a temporary magnet, making it useful in metalworking and repair.

Where does magnetiser come from?
The word is formed from magnetise, with the suffix -er denoting an instrument, device, or person that performs an action. Magnetise ultimately derives from magnet, which comes through Latin from the Greek magnētis, meaning "lodestone" or "magnet." The British spelling uses the -ise form, while North American usage commonly spells the corresponding words with -ize.
