Options:

Correct Answer: μ₀ times the total current through the loop

Solution:

Ampere\'s Law states that the line integral of B around a closed loop is μ₀ times the total current through the loop.

According to Ampere's Law, what is the line integral of the magnetic field around a closed loop equal to?

According to Ampere's Law, what is the line integral of the magnetic field around a closed loop equal to?

Step 1: Understand that Ampere's Law relates the magnetic field (B) to electric current.
Step 2: Recognize that a closed loop is an imaginary path that forms a complete circle.
Step 3: Know that the line integral of B means you are adding up the magnetic field along that closed loop.
Step 4: Identify that μ₀ is a constant called the permeability of free space, which helps relate current to magnetic fields.
Step 5: Realize that the total current through the loop is the sum of all currents that pass through the area enclosed by the loop.
Step 6: Combine these ideas to conclude that the line integral of B around the closed loop equals μ₀ times the total current through the loop.

Ampere's Law – Ampere's Law relates the magnetic field around a closed loop to the electric current passing through the loop, expressed mathematically as the line integral of the magnetic field B being equal to μ₀ times the total current I enclosed by the loop.
