electromagnetismn.

Brit.

/ᵻˌlɛktrə(ʊ)ˈmaɡnᵻtɪz(ə)m/, U.S.

/əˌlɛktrəˈmæɡnəˌtɪz(ə)m/,

/iˌlɛktrəˈmæɡnəˌtɪz(ə)m/

Origin: Formed within English, by compounding; probably modelled on a French lexical item. Etymons: electro- comb. form, magnetism n.

Etymology: < electro- comb. form + magnetism n., probably after French électro-magnétisme (1781), although the term was only in isolated use in any language before the discoveries of the Danish scientist H. C. Ørsted in 1820. Compare German Elektromagnetismus (1820 in a translation of Ørsted, from a Danish original of the same year), Danish elektromagnetisme (probably 1820), and also post-classical Latin magnetismus electri , magnetismus electricorum (both 1641). Compare slightly earlier electromagnetic adj.

Physics.

Electromagnetic phenomena and properties; the branch of physics that deals with these.
