Noun
the lines of force surrounding a permanent magnet or a moving charged particle
Source: WordNetIt is just as foolish to complain that people are selfish and treacherous as it is to complain that the magnetic field does not increase unless the electric field has a curl. Both are laws of nature. John von Neumann
What lead me more or less directly to the special theory of relativity was the conviction that the electromotive force acting on a body in motion in a magnetic field was nothing else but an electric field. Albert Einstein
The application of a strong magnetic field enables the measurement of the energy of the most penetrating particles to be carried out, and the method may be capable of still further extension and improvement. Victor Francis Hess
The continental drift theory is designed to avoid two problems for the evolutionists. One, the magnetic field is getting weaker. Number two, there is very little sediment in the ocean. And another explanation for that might be that the Bible is right and the Earth is not billions of years old. Kent Hovind
Words have no single fixed meaning. Like wayward electrons, they can spin away from their initial orbits and enter a wider magnetic field. No one owns them or has a proprietary right to dictate how they will be used. David Lehman
According to well-known electrodynamic laws, an electron moving in a magnetic field is acted upon by a force which runs perpendicular to the direction of motion of the electron and to the direction of the magnetic field, and whose magnitude is easily determined. Pieter Zeeman
