Understanding Coercivity?

Hysteresis of soft and hard magnetic materials. Soft magnetic materials have a tall, narrow hysteresis loop due to their low Coercivity and Hard magnetic materials have a tall, but wide hysteresis loop due to their high Coercivity.
Comparison of Small Coercive Force of Soft Ferromagnetic Materials with the Large Coercive Force of Hard Ferromagnetic Materials


What is Coercivity?

What is Coercivity? When we apply an outside magnetic field to a magnetic material, we are forcing it -coercing it- to become magnetized. how much of an applied field is required to demagnetize the material?

The Hysteresis Loop Explained - Understanding Hysteresis and BH Curves

Hysteresis is based on a Greek word that means lagging. So Magnetic Hysteresis is all about how a material's magnetic properties lag behind the force that creates those properties.  The hysteresis curve tells us a lot about a material's response to a magnetic field, so if we know how to interpret it, we will know and understand a lot about the material's response to magnetic input.

Rare Earth Metals -12 Things You Didn’t Know

Image
Rare Earth Metals have become very important to our high-tech economy in recent years. Many new uses have been found for rare earths and they are found both in everyday applications like mobile phones and computers and very special technologies, like anti-counterfeiting. They occupy that strange part at the bottom of the Periodic Table that looks almost like a footnote. It’s the part with the longest, most unpronounceable names of elements that you probably ignored when you were in science class..
