      n[U] the science of magnetism and electrical currents
      Electromagnetism is the study of the electromagnetic force which is a type of physical interaction that occurs between electrically charged particles.
      The electromagnetic force usually shows electromagnetic fields, such as electric fields, magnetic fields and light.
      The electromagnetic force is one of the four fundamental interactions in nature. The other three fundamental interactions are the strong interaction, the weak interaction, and gravitation.
      The word electromagnetism is a compound form of two Greek terms, ἢλεκτρον, ēlektron, "amber", and μαγνήτης, magnetic, from "magnítis líthos" (μαγνήτης λίθος), which means "magnesian stone", a type of iron ore.
      The science of electromagnetic phenomena is defined in terms of the electromagnetic force, sometimes called the Lorentz force, which includes both electricity and magnetism as elements of one phenomenon.
      An electromagnet is a magnet that consists of a piece of iron or steel surrounded by a coil. The metal becomes magnetic when an electric current is passed through the coil.

      While anti-statism is central, anarchism entails opposing authority or hierarchical organisation in the conduct of human relations, including, but not limited to, the state system.
      As an anti-dogmatic philosophy, anarchism draws on many currents of thought and strategy.
      Anarchism does not offer a fixed body of doctrine from a single particular world view, instead fluxing and flowing as a philosophy.

      Mercury fulminate is a primary explosive. It is highly sensitive to friction and shock and is mainly used as a trigger for other explosives in percussion caps and blasting caps.
      First used as a priming composition in small copper caps after the 1830s, mercury fulminate quickly replaced flints as a means to ignite black powder charges in muzzle-loading firearms.
      Mercury fulminate has the distinct advantage over potassium chlorate of being non-corrosive, but it is known to weaken with time.
      Today, mercury fulminate has been replaced in primers by more efficient chemical substances. These are non-corrosive, less toxic and more stable over time.
      Fulminates are chemical compounds which include the fulminate ion. The fulminate ion is a pseudohalic ion, acting like a halogen with its charge and reactivity.
