Ferrite cores have to meet mechanical requirements during assembling and for a growing number of applications. Since ferrites are ceramic materials one has to be aware of the special behavior under mechanical load. As valid for any ceramic material, ferrite cores are brittle and sensitive to any shock, fast changing or tensile load. Ferromagnetic-core or iron-core inductors use a magnetic core made of a ferromagnetic or ferrimagnetic material such as iron or ferrite to increase the inductance.

Jan 31, 2012 · Designing a ferrite based inductor that will saturate by less than 10% is a fairly straightforward process. Once size constraints are determined an inductor core can be chosen and then Equation 2 can be used to calculate the number of turns necessary to support the required inductance and peak current with a 10% or less drop in inductance. The inductance was measured with different numbers of turns on the core. This was done for both an ungapped core and a gap of 0.06mm. The inductance is shown in Fig. 5. The inductance factor, AL, measured in nH, is calculated from the inductance & number of turns and is shown in Fig. 6. The inductance factor is used in the equation L= AL*N Inductance, core size, and permeability are now known.

In general, if there's DC in the winding use a dust core, a core with a physical gap, or an air core. Ferrite is a ceramic material. Ferrite bar or rod based (loop-stick) antennas are useful too, however, making them bigger does not make them better in the same way as can be achieved with long wire and 'air core' loop antennas, because no matter how thick or how long a ferrite rod is made, its ability to transduce radio 'waves' is not improved, this being why I always used ...
