   Q1. A person holds a magnet near a coil of wire. What is the result if the coil is made of a ferromagnetic material?

   • A) The coil produces a weaker magnetic field due to the reduced magnetic permeability.
   • B) The coil produces a stronger magnetic field due to the increased magnetic permeability.
   • C) The coil's magnetic field is unaffected by the material.
   • D) The coil's magnetic field is reversed due to the increased magnetic permeability.

   Answer: The coil produces a stronger magnetic field due to the increased magnetic permeability.

   Explanation: A coil made of a ferromagnetic material produces a stronger magnetic field due to the increased magnetic permeability.
