Web3 de nov. de 2024 · Take a length of wire, hook it up to an ammeter (something that measures current), and place it between the poles of a magnet. Now move the wire sharply through the invisible magnetic field the magnet produces and a current will briefly flow through the wire (registering on the meter). WebHe also compared the magnet’s polarity to the polarity of the Earth, and developed an entire magnetic philosophy on this analogy. Gilbert’s findings suggested that magnetism was the soul of the Earth, and that a perfectly spherical lodestone , when aligned with the Earth’s poles, would spin on its axis, just as the Earth spins on its axis over a period of 24 hours.
