question: Vilken av de visade bilderna representerar bäst fenomenet induktion?
context: Electromagnetic induction
  Michael Faraday anses allmänt ha upptäckt induktionen 1831, och James Clerk Maxwell beskrev den matematiskt som Faradays induktionslag. Lenz' lag beskriver riktningen på det inducerade fältet. Faradays lag generaliserades senare och blev Maxwell-Faraday-ekvationen, en av de fyra Maxwell-ekvationerna i hans teori om elektromagnetism.

  Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. Lenz's law describes the direction of the induced field. Faraday's law was later generalized to become the Maxwell–Faraday equation, one of the four Maxwell equations in his theory of electromagnetism.
