Question: What is the effect of increasing the area of a loop in a uniform magnetic field on the magnetic flux?

Options:

  1. Magnetic flux increases
  2. Magnetic flux decreases
  3. Magnetic flux remains constant
  4. Magnetic flux becomes zero

Correct Answer: Magnetic flux increases

Solution:

Increasing the area of the loop in a uniform magnetic field increases the magnetic flux, as magnetic flux is given by the product of the magnetic field strength and the area.

Questions & Step-by-Step Solutions

What is the effect of increasing the area of a loop in a uniform magnetic field on the magnetic flux?
Correct Answer: Magnetic flux increases.
  • Step 1: Understand what magnetic flux is. Magnetic flux is a measure of how much magnetic field passes through a certain area.
  • Step 2: Know the formula for magnetic flux. The formula is: Magnetic Flux (Φ) = Magnetic Field Strength (B) × Area (A).
  • Step 3: Identify the components in the formula. Here, B is the strength of the magnetic field, and A is the area of the loop.
  • Step 4: Consider what happens when you increase the area (A) of the loop. If you make the area larger while keeping the magnetic field strength (B) the same, you are multiplying a larger number by the same B.
  • Step 5: Conclude that increasing the area results in a larger product. Therefore, the magnetic flux (Φ) increases when the area of the loop increases in a uniform magnetic field.
