Ferrite looks like a ceramic with magnetic properties, It is used in many electronic devices. Chemically, it's M(Fe(sub x)O(sub y)), M being any metal that forms divalent bonds.
Ferrites have very high magnetic permeability and electrical resistance. The high magnetic permeability is important in high frequency devices such as antennas.
Ferrite Rings are used as cores for homemade Transformers. This type of experiment and construction is very common in Ham Radio.

What is the plastic barrel thing on the end of miniUSB cables for?
It's probably an iron ferrite ring. These are used to remove the effects of crosstalk from the wires before they reach the computer or device.
What is calcium ferrite?
calcium ferrite is CaFe2O4
How to use a ferrite core?
Ferrite cores are used to suppress electrical noise on conductors. A split ferrite is installed over a conductor as close to the source of noise as possible. A solid ferrite has the conductor routed through it, it may also have several turns of the conductor looped through the donut shaped ferrite. Take a look at a motherboard and you'll see ferrites in use in the power supplies.
Why does a voip phone require a ferrite clamp?
Ferrite
How do I convert a Ferrite number into a percentage?
While there is no direct correlation, with higher ferrite numbers ( >30) a factor of 0.7 can be applied to produce % ferrite.
What is the barrel found near one end on some USB cables?
It's called a "ferrite core" or "ferrite choke." It is used to filter out electrical noise that might interfere with the USB signal.
What is the difference between an alnico magnet and ferrite magnet?
The term alnico is derived from the names of three metals, aluminum, nickel, and cobalt, which can be used to make an alloy that has useful magnetic properties. Ferrite is a form of iron. Alnico magnets are more powerful and more expensive than ferrite magnets.
What is the purpose of Ferrite test?
The amount of ferrite present in austenitic or duplex stainless steels is called "FN" or Ferrite Number. For austenitic SS, a small amount of ferrite will decrease the tendency for hot cracking during solidification. Company specifications should have a required FN range in their welding specs. Too low of a number may indicate that there are hot cracks. Too high of a number may decrease the corrosion resistance, or the ferrite can convert to sigma at higher temperatures. Ferrite is magnetic whereas austenite is not. Duplex SS nominally contains 50% ferrite/austenite, although the acceptable range for ferrite is much broader than exactly 50%. There are several ways to measure the FN. As mentioned by Metalguy, you can use a Magne-Gage. I have used a Severn Gage and a Feritscope.
What oxide consisting of iron and another metal such as nickel is used in making magnets and aerials?
Ferrite
When was Zanoni Ferrite born?
Zanoni Ferrite was born in 1946, in So Paulo, SP, Brazil.
Which is more soft phase ferrite or austenite in iron carbon diagram?
Pretty sure it is ferrite
How to measure the ferrite number?
You can measure the ferrite number of a steel using a Severn Gage, a mechanical device; or using a ferrite scope, an electronic device, available from several manufacturers.
