Free ferrite is ferrite that is structurally separate and distinct, as may be formed without the simultaneous formation of carbide when cooling hypoeutectoid austenite into the critical temperature range. Free ferrite is a relatively pure metallic iron phase present in steel or cast iron. There is a ferrite below/above the tx/rx coil. The peak-peak current is ca. 5A (measured). The tx coil has 5 windings the rx coil has 20 windings. What I'm primarily interested in is the total current in the rx coil. Secondarily about the losses in the copper plane close to it (not visible yet) Is there a reason I could not simulate this with FEMM?

TDK offers a wide variety of Mn-Zn ferrite materials optimized for their application purposes. The products are also available in various profiles, including materials with standard shapes that are compliant with international standards as well as unique and specialized shapes. The obvious advantages of these new materials are in high frequency applications with their high induction, high permeability and low core loss. There are four amorphous materials that have been used in high frequency applications: 2605SC, 2714A, 2714AF and Vitroperm 500F.

The software program finite element method magnetics (FEMM) Magnetic fields are solved using the program Finite Element Method Magnetics (FEMM) in of inset ferrite permanent magnets synchronous motor with distributed winding on the stator. FEMM is a set programs on solve static and low frequency magnetic fields. A common task that FEMM might be applied to is the calculation of the inductance of a gapped inductor. Although the inductance can be estimated using simple magnetic circuit theory, the circuit approach typically ignores flux leakage and fringing effects. To resolve these non-ideal effects in more detail a finite element analysis can be employed. Hi I am trying to model a small single winding inductor wound on a ferrite core. The operating frequency is 100kHz. So far the model does not give the expected answer and I can only assume that this is because my ferrite material model is incorrect. Has anyone found a way of successfully modelling ferrites.

Soft ferrite is a ferrimagnetic material, and is composed primarily of iron, typically combined with nickel and zinc (NiZn) or manganese and zinc (MnZn) though some applications require the use of more expensive metals such as cobalt, titanium, or silicon.1 The magnetism results from the nature of transition metals; transition metals have a ... Ferrite magnets can be produced in many shapes and sizes. Machining to size is limited to grinding processes - the electrically insulating Ferrite material does not allow wire spark erosion. As such, the main shapes are blocks, discs, rings, arcs, and rods. Other shapes and custom sizes may well be possible but tooling charges may apply. A simplified model and an equivalent circuit is also discussed. The second part describes several ferrite cored inductors, along with measurements of inductance and Q. The third part displays graphs of flux density, flux lines, inductance and Q of several ferrite cored inductors.

Nonlinear material properties, known only through measurements. Models are behavioral, based on measurements. Physics‐based micromagnetic models exist, but can’t address ferrite loss yet. Circuit models based on RLC elements only can’t capture nonlinear behavior. power.thayer.dartmouth.edu 2 May 29, 2009 · 6 – you should have a good representation of your magnet (a 2-D figure that is a closed line). Now put a “Block Label” (button with a circle and square) in the centre of the magnet. Open its properties and pick the new ferrite material you created. You may have to adjust “Magnetization Direction” (in degrees) and “Mesh Size”, or not.
