Q: According to Ampere's Law, the line integral of the magnetic field B around a closed path is equal to what?
Solution: Ampere's Law states that the line integral of the magnetic field B around a closed path is equal to μ₀ times the total current I enclosed by the path.
Steps: 5
Step 1: Understand that Ampere's Law relates the magnetic field to electric current.
Step 2: Know that the line integral of the magnetic field B means you are measuring the magnetic field along a closed loop.
Step 3: Recognize that μ₀ is a constant called the permeability of free space, which helps relate magnetic fields to currents.
Step 4: Identify that the total current I is the sum of all currents that pass through the area enclosed by the closed path.
Step 5: Combine these ideas to understand that Ampere's Law states: the integral of B around a closed path = μ₀ × total current I enclosed.
