1. Question 1

   Q1. A device uses electromagnetic induction to transfer energy between coils. What is the primary advantage of using a transformer with a high number of turns?

   • A) The transformer produces a weaker magnetic field due to the reduced number of turns.
   • B) The transformer produces a stronger magnetic field due to the increased number of turns.
   • C) The transformer's ability to transfer energy is reduced due to the increased number of turns.
   • D) The transformer's efficiency is increased due to the increased number of turns.

   Answer: The transformer produces a stronger magnetic field due to the increased number of turns.

   Explanation: A transformer with a high number of turns produces a stronger magnetic field, enabling efficient energy transfer.
