magnetic moment
"Dynamics of the magnetic moment. A magnetic moment is like a spinning top, which is driven by the local effective magnetic field and subject to damping"
The magnetic moment (or magnetic dipole moment) is a vector. The direction of the magnetic moment is the direction of the area of the loop as defined by the right-hand rule. Curl the fingers of your right hand in the direction of the current flow. Your thumb points into the direction of the magnetic moment.
METAMIA is a free database of analogy and metaphor. Anyone can contribute or search. The subject matter can be anything. Science is popular, but poetry is encouraged. The goal is to integrate our fluid muses with the stark literalism of a relational database. Metamia is like a girdle for your muses, a cognitive girdle.
