The problem which an air gap solves in a core is the excessive flux produced by a high level of current in the windings. Transferring the previous analogy, suppose that your windings produce an MMF of 12 ampere turns and that your magnetic core (your 'load') has a reluctance of two ampere-turns per weber. However, a flux of six webers is too ...

remember making nickel zinc ferrite by ball milling red iron oxide, green nickel oxide and white zinc oxide, together, and firing the. powder in a pottery kiln in ceramic crucibles. The sintered powder. was black and a lot coarser than the starting powder and had measured. magnetic properties very similar to commercial nickel zinc ferrite.

If your talking about hard ferrite (ceramic) magnets, cutting & machining is not an option. The main method is grinding, which limits one to making only simple shapes. Also, it's much easier to grind them when the are not magnetized. MJR2 (Mechanical) 21 Jun 07 08:21 Using a wet diamond blade by hand works just fine. For straight cuts that is.

Grinding works, but you can call Farnell or the like and get them already gapped too. So you could find and buy 100 pre-gapped cores and have 100 sets to use. As to the grinding, abrasive cloth on a rubber stab works, but precision is a grind-test-grind-test matching and culling hand operation. Some transformer houses might sell you a gapped core.

Getting the gap dimension is fairly simple too. The basic formula is: -. μ e = μ i 1 + G ⋅ μ i l e. Where G is gap and l e is effective length of the core. μ i is initial permeability (before gapping) and μ e is effective permeability (after gapping).

post sintered cores cannot use in the application due to uneven surface & un- gapped (uneven surface makes the cores produce fluctuating inductance that is dangerous to the circuits) post grinding cores (bottom & top) cannot use in the application due to un- gapped cores (cores needs to be gapped in the limbs to make them produce the designed .

Member. Joined: Jan Mon 31, 2022 6:56 pm. Posts: 91. Location: WA, USA. I'm curious about this, because information seems a bit thin on the ground- and most of what you can find on the googles is more geared toward modern coil cores and so forth. I am guessing based on what I know that most tuning slugs would be made of ferrite- but I'm curious ...

The vast (order of magnitude) difference in core loss between different core material types certainly suggests that ferrite would be a preferred material to powder cores. If core loss alone were considered, that would certainly be true. 0.1 1 10 100 Current (A) Inductance (µH) 0.2 0.5 0.4 0.3 0.1 MVR1251T-361 MVR1247C-361 Figure 1.
