Flux Definition and Ratios
The question asks for the term representing the ratio of total flux linkage to used flux.
- Total Flux Linkage: This refers to the overall magnetic flux generated.
- Used Flux: This is the portion of the total flux that successfully links with the intended circuit or coil.
The ratio between the total flux and the flux that actually links the circuit indicates how much flux is "lost" or "leaking" away from the intended path.
Understanding Flux Leakage Factor
The term that precisely defines the ratio of total flux linkage to used flux is the flux leakage factor.
This factor quantifies the extent of magnetic flux that does not follow the intended path, often bypassing the core or useful part of a magnetic circuit. A higher leakage factor implies that a significant portion of the generated flux is not effectively utilized.
Therefore, the correct term is the flux leakage factor.
Important Questions from Magnetic Flux Density
The magnetic flux Φ(in Web) linked with a single turn coil at an instant of time t (in second) is given by Φ(t) = 2t 2– 20t + 40. The induced EMF in the coil at the instant t = 2 seconds is
What does the remanence (Br) indicate in a magnetic hysteresis loop?
A coil is placed in a uniform magnetic field. If the area of the coil is doubled while the magnetic field strength and orientation remain unchanged, how will the magnetic flux through the coil be affected assuming the initial magnetic flux is a non-zero finite value?
