Questions & Step-by-Step Solutions
According to Ampere's Law, the line integral of the magnetic field B around a closed loop is equal to what?
Step 1: Understand that Ampere's Law relates the magnetic field (B) to electric current.
Step 2: Recognize that the line integral (∮B·dl) means you are adding up the magnetic field along a closed loop.
Step 3: Know that μ₀ is a constant called the permeability of free space, which helps relate magnetic fields to currents.
Step 4: Identify that I_enc represents the total electric current that is enclosed by the loop you are considering.
Step 5: Put it all together: Ampere's Law states that the total magnetic field around a closed loop is equal to μ₀ times the total current inside that loop.
Ampere's Law – Ampere's Law relates the magnetic field around a closed loop to the electric current passing through that loop.
Line Integral – The line integral of a vector field along a curve measures the cumulative effect of the field along that path.
Enclosed Current – I_enc represents the total current that passes through the surface bounded by the closed loop.
