Electricity and magnetism
Electricity and
magnetism
are manifestations of a single underlying electromagnetic force. Electromagnetism is a branch of physical science that describes the interactions of electricity and magnetism, both as separate phenomena and as a singular electromagnetic force. A
magnetic field
is created by a moving electric current and a magnetic field can induce movement of charges (electric current). The rules of electromagnetism also explain geomagnetic and electromagnetic phenomena by explaining how charged particles of atoms interact.
Before the advent of technology, electromagnetism was perhaps most strongly experienced in the form of
lightning
