Current Pins and Buttons
Description: This scientific diagram shows a straight wire carrying a current I, circled by three rings of magnetic field B with arrows, above Ampère's law ∮ B · dl = μ₀ I, on a deep dark background. André-Marie Ampère (1775–1836) founded electrodynamics by showing how electric currents create magnetic fields. The unit of electric current, the ampere, is named in his honor. Made for electricians, electrical engineers and anyone powered by curiosity, it suits a workshop, lab, study or office.
