Jessica Kormos. As one of the basic passive components, inductors fill an important role in electronics applications, from starting engines to delivering power to your house. Inductors store energy in a magnetic field when current flows through it. A typical inductor uses insulated wire wrapped into a coil around a central core.

An engineering definition of inductance is Equation 7.12.2 7.12.2, with the magnetic flux defined to be that associated with a single closed loop of current with sign convention as indicated in Figure 7.12.1 7.12. 1, and N N defined to be the number of times the same current I I is able to create that flux.

Feb 2, 2018. #17. Cubrilo said: Inductor energy storage cannot compete capacitor in principle (if you think of it) due to its "dynamic nature" - it needs current to run so electrons are colliding all the time producing losses in the conductor, whereas capacitor needs just a tiny leakage current to stay charged.

If there is appropriate symmetry, you may be able to do this with Ampère''s law. Obtain the magnetic flux, Φm Φ m.

The energy storage inductor in a buck regulator functions as both an energy conversion element and as an output ripple filter. This double duty often saves the cost of an additional output filter, but it complicates the process of finding a good compromise for the value of the inductor.
