Magnetism

attraction for iron; associated with electric currents as well as magnets; characterized by fields of force

磁性，磁力；磁学；吸引力

magnetic field

Magnetism can’t be seen but the area around a magnet where its influence can be detected is called the magnetic field；the lines of force surrounding a permanent magnet or a moving charged particle；an area around a magnet or magnetic object, where there is a force that will attract some metals towards i

[电磁] 磁场

flux lines

A magnetic field is made up of imaginary lines called flux lines.

Right Hand Grip Rule

The Ampere rule (also known as the Right hand grip rule) is a rule that describes the relationship between the current and the direction of the magnetic induction line in the magnetic field that the current excites.

通电直导线中的安培定则，也称作安培定则一，其[1]规则是：用右手握住通电直导线，让大拇指指向电流的方向，那么四指指向就是磁感线的环绕方向。通电螺线管中的安培定则，即安培定则二，其规则是：用右手握住通电螺线管，让四指指向电流的方向，那么大拇指所指的那一端是通电螺线管的N极。

internal combustion engine

The internal combustion engine is an engine in which the combustion of a fuel (normally a fossil fuel) occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine (ICE) the expansion of the high-temperature and high-pressure gases produced by combustion apply direct force to some component of the engine.
