Iron Core
The cross-sectional area of iron core is an essential and crucial parameter to solenoid valve. The difference between main pole area (S m) and vice pole area (S v) will induce the variations of magnetic flux density and further influence the F e.According to the vertical view of iron core (Fig. 5), S m is influenced by inner radius (R 1) and outer radius (R 3) of main pole; S v. is …

Optimal design of transcranial magnetic stimulation coil with iron core
According to the performance factor, both iron core coils obtain the best overall performance with a fill factor 0.4 and the two legs of the iron core close to the inner sides of the coil. Finally, three prototypes are constructed—the basic, optimized, and full-size slinky iron core coil—and magnetic field detection demonstrates a good agreement with the simulation results.
Transformers | Cambridge (CIE) IGCSE Physics Revision Notes …
Operation of a transformer. Extended tier only. An alternating current is supplied to the primary coil. The current is continually changing direction. This means it will produce a changing magnetic field around the primary coil. The iron core is easily magnetised, so the changing magnetic field passes through it. As a result, there is now a changing magnetic field …
Which, Foil Air Core or Iron Core Inductors
The DCR for the air core is 0.141 and for the iron core about 0.05. The speaker will be supported by an 80 watt / channel OTL tube amp. The iron core inductor is rated for 500 watts, but have reportedly been tested at up to 1000 watts with no core saturation. A general rule seems to be, always go air core and foil if possible.
Coil Inductance Calculator
Hello sir, do you think a 100 Henries inductor coil normal? The inductor is a common school use transformer 5000 turn coil, with wire diameter about 0.15mm, the official air-core value is 0.6H, however when I calculate the iron core got a result of 105H. Could this be possible? So it suggests the permeability of the iron core is about 175

Using Air core inductors (instead of original iron core)
I bought the copper wire and iron cores today, both things were cheap, I see money is not an issue in this 2 small inductors (approx $20 on materials for 4 inductors, 2 air core 1mH, 2 iron core 1.5mH). Actually, I think that dealing with the iron core will be more expensive to me than just winding an air core coil (time is money).

Air Core vs Iron Core
This is a regular E/I core, with the I''s placed on the opposite side of the E fingers. Means the air gap is basically infinite. The useful bit comes from the linerization of the inductance in the coil, due to the support from the core that cannot saturate. Take any air coil and a decent inductance bridge and sit and unwind the coil one turn at ...
