我們都聽說過。光子不僅僅是光的微粒,它們介導帶電粒子之間的基本相互作用,使正電子吸引電子,使質子排斥旁邊的質子。電場和磁場以前是分開處理的,但是邁克爾·法拉第和詹姆斯·克拉克·麥克斯韋的工作將他們統一起來。法拉第實驗了電和磁,他注意到如果一個人能在電流的同時施加磁場,他可以改變現有的電場和磁場。同樣可以通過對磁通源施加電場來實現。這表明存在一種力,可以通過電流的變化引起磁通量的變化,反之亦然,麥克斯韋將用數學的方法來表達這些現象,以證明電磁場會從正電荷點流向負電荷點,從而使得…更正電子的野鷹
The one we've all heard of. Photons are more than simply corpuscles of light, they mediate the fundamental interactions between charged particles, making the positron attract the electron and making the proton repel the proton next to it.Electric fields and magnetic fields were previously treated separately, but it was the work of Michael Faraday and James Clerk-Maxwell which was to unify them. Faraday experimented with electricity and magnetism, and he noticed that if one could apply a magnetic field alongside an electrical current, he could deviate both the electric and magnetic fields present. The same could be done by applying an electrical field to a source of magnetic flux. This proposed that there existed a force which would induce a change in magnetic flux from a change in an electrical current, and vice versa. maxwell was to express these phenomena mathematically, to show that an electromagnetic field would flow from a positive to negative charge point, such that the ... more - PositronWildhawk
