| magnetic moment | <physics> (a) A vector associated with a magnet, current loop, or particle, the cross product of this vector with the magnetic field is equal to the torque which the field exerts on the system. (b) The adiabatic invariant associated with the rapid gyromotion of a charged particle in a slowly varying magnetic field. (The value of the magnetic moment in sense (b) is the magnitude of the vector in sense (a).) (13 Nov 1997) |
| moment | 1. A minute portion of time; a point of time; an instant; as, at thet very moment. "In a moment, in the twinkling of an eye." (1 Cor. Xv. 52) 2. Impulsive power; force; momentum. "The moments or quantities of motion in bodies." (Berkley) "Touch, with lightest moment of impulse, His free will." (Milton) 3. Importance, as in influence or effect; consequence; weight or value; consideration. "Matters of great moment." (Shak) "It is an abstruse speculation, but also of far less moment and consequence of us than the others." (Bentley) 4. An essential element; a deciding point, fact, or consideration; an essential or influential circumstance. 5. <mathematics> An infinitesimal change in a varying quantity; an increment or decrement. 6. <mechanics> Tendency, or measure of tendency, to produce motion, especially. Motion about a fixed point or axis. Moment of a couple, the product of the intensity of the force into the perpendicular distance from the point to the line of direction of the force, the product of that component of the force which is perpendicular to the plane passing through the line and the point of application of the force, into the shortest distance between the line and this point, the product of the force into the perpendicular distance of its point of application from the plane. Moment of inertia, of a rotating body, the sum of the mass of each particle of matter of the body into the square of its distance from the axis of rotation; called also moment of rotation and moment of the mass. Statical moment, the product of a force into its leverage; the same as moment of a force with respect to a point, line, etc. Virtual moment. See Virtual. Synonym: Instant, twinkling, consequence, weight, force, value, consideration, signification, avail. Origin: F. Moment, L. Momentum, for movimentum movement, motion, moment, fr. Movere to move. See Move, and cf. Momentum, Movement. Source: Websters Dictionary (01 Mar 1998) |
| product-moment correlation | A statistical procedure which yields the correlation coefficient referred to as r (-1.00 to +1.00) and involves the actual values, rather than the ranks (rank order) of the measurements. (05 Mar 2000) |
| overturning moment | <radiobiology> Torque (moment) on a toroidal field coil in a tokamak, about the device's radial direction, that results from out-of-plane forces on the coil due to the interactions between the coil current and the poloidal (vertical) magnetic field. This torque tends to overturn the vertical toroidal field coil, and must be engineered against. (09 Oct 1997) |

| dipole moment |
A dipole (Greek: dyo = two and polos = pivot) is a pair of electric charges or magnetic poles of equal magnitude but opposite polarity (opposite electronic charges), separated by some (usually small) distance. Dipoles can be characterized by their dipole moment, a vector quantity with a magnitude equal to the product of the charge or magnetic strength of one of the poles and the distance separating the two poles. ...

| dipole moment |
Without qualification usually means electric dipole moment, the product of charge and separation distance of an (electric) dipole. Dipole moment is a vector, its direction determined by the position vector from the negative to the positive charge. ...

| dipole moment |
When a molecule has some charge separation (usually because the molecule is polar), it's said to have a dipole moment.
