磁场

感受到在玻璃下方的磁铁所产生的强烈磁场,在玻璃上方的铁磁流体,会显示出正常场不稳定性。
最早出现的几副磁场绘图之一,绘者为勒内·笛卡儿,1644年。这绘图显示出地球(中心大圆球)的磁场吸引几块圆形磁石(以I、K、L、M、N标记的圆球)。笛卡儿认为磁性是由微小螺旋状粒子的环流造成的,称为「螺纹子」。这些螺纹子穿过磁铁的平行螺纹细孔,从指南极(A)进入,从指北极(B)出来,经过磁铁外的空间(G、H)再绕回指南极。当螺纹子绕动至磁石附近时,会穿过其细孔,从而造成磁力。
透过铁粉显示出的磁场线。
指南针显示出一个条形磁铁的磁场方向。指南针的指北极(红色)会被磁铁的指南极(S极)吸引,也会被磁铁的指北极(N极)排斥。

在电磁学里,磁石、磁铁、电流及含时电场,都会产生磁场。处于磁场中的磁性物质或电流,会因为磁场的作用而感受到磁力,因而显示出磁场的存在。磁场是一种矢量场;磁场在空间里的任意位置都具有方向和数值大小。

磁铁与磁铁之间,通过各自产生的磁场,互相施加作用力和力矩于对方。运动中的电荷会产生磁场。磁性物质产生的磁场可以用电荷运动模型来解释。

当施加外磁场于物质时,磁性物质的内部会被磁化,会出现很多微小的磁偶极子。磁化强度估量物质被磁化的程度。知道磁性物质的磁化强度,就可以计算出磁性物质本身产生的磁场。产生磁场需要输入能量,当磁场被湮灭时,这能量可以再回收利用,因此,这能量被视为保存于磁场。

Magnetic field 磁场

Magnetic field of an ideal cylindrical magnet with its axis of symmetry inside the image plane. The magnetic field is represented by magnetic field lines, which show the direction of the field at different points.
One of the first drawings of a magnetic field, by René Descartes, 1644. It illustrated his theory that magnetism was caused by the circulation of tiny helical particles,
Hans Christian Ørsted, Der Geist in der Natur, 1854
Compasses reveal the direction of the local magnetic field. As seen here, the magnetic field points towards a magnet's south pole and away from its north pole.

A magnetic field is the magnetic effect of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field. The term is used for two distinct but closely related fields denoted by the symbols B and H, where H is measured in units of amperes per meter (symbol: A·m or A/m) in the SI. B is measured in teslas (symbol:T) and newtons per meter per ampere (symbol: N·m·A or N/(m·A)) in the SI. B is most commonly defined in terms of the Lorentz force it exerts on moving electric charges.
