Part 3/10:
Maxwell's exploration into electromagnetism was stimulated by earlier contributions from a range of scientists. The stage was set with Charles-Augustin de Coulomb’s inverse square law of electrical forces between stationary charged particles, leading to the advent of early batteries by Alessandro Volta, and culminating with Hans Christian Ørsted's discovery of the relationship between electric current and magnetic fields. These findings laid the groundwork for Maxwell’s monumental insights.
