Of or pertaining to equal force.
1. Phys. Geog., etc. Indicating equal (magnetic) force; applied to lines connecting points (of the earth's surface, etc.) at which the intensity of the magnetic force is the same; or to a map or chart on which such lines are marked. Also as n. An isodynamic line.
1837Brewster Magnet. 254 M. Hansteen has projected on a map of the globe the lines passing through the places in which the [magnetic] intensity has the same value. These lines he calls isodynamic lines or those of equal force, and they are, generally speaking, nearly parallel to each other, and to the lines of equal dip. 1839Sabine (title) Report on the Magnetic Isoclinal and Isodynamic Lines in the British Islands. 1857Whewell Hist. Induct. Sc. (ed. 3) III. 52 The intensity of the magnetic force is expressed by charts..on which are drawn the isodynamic..curves.
2. Of equal force, value, or efficacy.
1842Blackw. Mag. LII. 729 Forty gallons of water..in the ‘Black Hole’ of Calcutta, would have been rated..as isodynamic with gold. |
