Which term is the complete path of magnetic lines of force in a magnetic circuit?

• A. Inductance
• B. Line of force
• C. Magnetic circuit
• D. Magnetic amplifier

Answer: (D)

The complete path that magnetic lines of force follow in a magnetic circuit is called the magnetic circuit. This is the closed loop through the magnetic material and any air gaps that guides the flux from the source back to it. A line of force is a single magnetic flux line, not the whole loop, so it doesn’t name the entire path. Inductance is a property that relates flux to current (how much flux links the circuit per ampere-turns), not the path itself. A magnetic amplifier is a device that uses saturable cores to modulate signals, unrelated to the term for the flux path.
