Question: If the current in a circular loop is doubled, what happens to the magnetic field at the center?
Options:
It doubles
It halves
It remains the same
It quadruples
Correct Answer: It doubles
Solution:
The magnetic field at the center of the loop is directly proportional to the current.

Questions & Step-by-Step Solutions
If the current in a circular loop is doubled, what happens to the magnetic field at the center?
Step 1: Understand that a circular loop of wire creates a magnetic field when current flows through it.
Step 2: Know that the strength of the magnetic field at the center of the loop depends on the amount of current flowing through the loop.
Step 3: Remember that if you double the current, the magnetic field strength also doubles.
Step 4: Conclude that if the current in the loop is doubled, the magnetic field at the center will also be doubled.
Magnetic Field in a Loop – The magnetic field at the center of a circular loop is directly proportional to the current flowing through the loop, as described by the formula B = (μ₀ * I) / (2 * R), where B is the magnetic field, I is the current, and R is the radius of the loop.
