Circuit law of Ampere
Understand the Problem
The question is referring to the concept of circuit theory, specifically aiming to understand the law associated with current flow in electrical circuits, which is likely referencing Ampère's Law. This law relates to the magnetic field generated by electric currents.
Answer
The line integral of the magnetic field around a closed loop equals the permeability of free space times the total current passing through the loop.
Ampère's circuital law states that the line integral of the magnetic field around a closed loop is equal to the product of the permeability of free space and the total current passing through the loop.
Answer for screen readers
Ampère's circuital law states that the line integral of the magnetic field around a closed loop is equal to the product of the permeability of free space and the total current passing through the loop.
More Information
Ampère's circuital law is a fundamental principle in electromagnetism, part of Maxwell's equations. It has applications in calculating magnetic fields in various configurations, like solenoids and toroids.
Tips
A common mistake is not considering only the currents that pass through the loop when applying Ampère's law.
