Inductance Variations in Air-Cored Coils: Why the Numbers Don't Always Match

AI Thread Summary
Inductance values for air-cored coils can vary with changing current due to the presence of leakage flux. This phenomenon necessitates the use of equal turns rather than actual turns for accurate inductance calculations. The discussion emphasizes that practical measurements often deviate from theoretical predictions. Understanding these discrepancies is crucial for precise applications in electrical engineering. Accurate modeling of inductance in air-cored coils requires consideration of these factors.

Why the values of inductance for an air-cored coil are not exactly the same for changing current across it in practice??
 
Engineering news on Phys.org


Because of leakage flux existing, the equal turn instead of actual turn shall be used for coil inductance calculation.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Weird near-field phenomenon I get in my EM simulation'

I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
