Which law of electromagnetism establishes that the line integral of magnetic field intensity around any closed loop is equal to the total current passing through the surface enclosed by the loop multiplied by the permeability of free space?
A. Faraday's law of induction
B. Gauss's law for magnetism
C. Ampere's circuital law✓ Correct Answer
D. Biot-Savart law
💡 Solution & Explanation
Ampere's circuital law relates the integrated magnetic field around a closed curve to the electric current traversing the surface bounded by that curve. Faraday's law calculates induced electromotive forces from changing magnetic flux linkages. Gauss's law for magnetism proves that magnetic monopoles do not exist by setting total closed-surface flux to zero. Biot-Savart law calculates magnetic field contributions generated by infinitesimal current element segments.
