In this scenario, Sahil uses a magnet to pull the iron disc out of the tank. The correct explanation for why the magnet was able to pull the iron disc from the tank involves understanding how magnetism works:
  • Magnetic Properties: Magnets can attract ferromagnetic materials (like iron, cobalt, and nickel). The iron disc is made of a ferromagnetic material, which is why the magnet was able to attract and move it.
  • Non-magnetic Materials: Both oil and plastic are non-magnetic materials. These substances do not become magnetized when exposed to a magnetic field. The magnetic field, however, can pass through these materials without being affected.
  • The Role of the Magnet: The magnet does not need to directly contact the iron disc (though it likely did). It can exert a magnetic force through the oil and plastic tank, which is why it was able to pull the iron disc out even though it's submerged in oil and behind the plastic tank.
Thus, magnetism can pass through the oil and plastic tank without being significantly weakened by these materials, making D the correct option.
