WebMagnets are objects that can exert an invisible force called magnetism, which pulls on some metals such as iron and nickel. Magnets cannot pull against anything made of wood or … 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.
