Question: What is the effect of increasing the number of turns in a coil on the magnetic field strength produced by it? (2022)

Options:

  1. Increases the field strength
  2. Decreases the field strength
  3. No effect
  4. Reverses the field direction

Correct Answer: Increases the field strength

Exam Year: 2022

Solution:

Increasing the number of turns in a coil increases the magnetic field strength produced by it, as the field strength is directly proportional to the number of turns.

Questions & Step-by-Step Solutions

What is the effect of increasing the number of turns in a coil on the magnetic field strength produced by it? (2022)
  • Step 1: Understand what a coil is. A coil is a wire wound in a spiral shape.
  • Step 2: Know that when electricity flows through the coil, it creates a magnetic field around it.
  • Step 3: Learn that the strength of this magnetic field depends on how many times the wire is wound into turns.
  • Step 4: Realize that more turns mean more loops of wire for the electricity to flow through.
  • Step 5: Understand that each loop contributes to the overall magnetic field strength.
  • Step 6: Conclude that increasing the number of turns in the coil increases the total magnetic field strength.
