Electromagnet cores | Physics Forums

Oct 30, 2005· The Softest pure Iron would probably be best for you, If you wanted the Magnetic perm to drop off suddenly then Ferrite would be better, Iron remains a little magnetic after the coil is shut off, This is one reason to use ferrite, Ferrite is lighter than Iron but isn't as influenced on the permability level, Hemitite can also substitute Ferrite.

Ferrite | iron oxide compound |

A ferrite is formed by the reaction of ferric oxide (iron oxide or rust) with any of a number of other metals, including magnesium, aluminum, barium, manganese, copper, nickel, cobalt, or even iron itself. A ferrite is usually described by the formula M(Fe x O y), where M represents any metal that forms divalent bonds, such as any of the elements mentioned earlier.

Siderite Wikipedia

Siderite is also the name of a type of iron meteorite. Siderite is a mineral composed of iron(II) carbonate (FeCO 3). It takes its name from the Greek word σίδηρος sideros, "iron". It is a valuable iron mineral, since it is 48% iron and contains no sulfur or phosphorus.

What are iron core linear motors?

In iron core linear motors, the windings are mounted in an iron lamination stack. Like the rotor and stator of a standard rotary motor, linear motors have a primary part, which contains windings, and a secondary part made of magnets.

Ferromagnetism Georgia State University

When ferromagnetic materials are used in applications like an ironcore solenoid, the relative permeability gives you an idea of the kind of multiplication of the applied magnetic field that can be achieved by having the ferromagnetic core present. So for an ordinary iron core you might expect a magnification of about 200 compared to the magnetic field produced by the solenoid current with just an air core.

Information About the Electric Iron Invention: How an ...

An electric Iron is a general appliance used to press the wrinkles out of the clothes. This works on the basis that the combination of heat and pressure removes wrinkles. The principle of the electric iron is that when current is passed through a coil, the coil gets red hot and transfers the heat to the base plate of the electric iron through conduction.

Yes, the shape of the iron core does matter. The more complete the circuit formed by the iron, the more field that you will get for a given coil and current. Solid copper wire is better because it can usually carry more current. It is best to have a large amount of copper to keep the resistance down.

Core (manufacturing) Wikipedia

A core is a device used in casting and moulding processes to produce internal cavities and reentrant angles (an interior angle that is greater than 180°). The core is normally a disposable item that is destroyed to get it out of the piece. They are most commonly used in sand casting, but are also used in die casting and injection moulding.

Regions of downwelling iron in the core can be associated with cold regions in the mantle, and core upwellings can be associated with hot regions in D″. Gubbins and Richards (1986) pointed out that if there are some topographic changes on the core–mantle boundary, then the gravitational equipotentials would not coincide with the isotherms. It would cause a mechanical interaction with the flow and a .
