What are the factors that determine the coercivity and remanence of magnetic materials? Are there any links between these factors? What is the connection?
Magnetism is powerful, look commonly Br (remanence), magnetism is lasting see Hc (coercive force).But note that when the magnet grades and sizes are determined, the values of the general Br and Hc are fixed. If you need to change, two values are proportional changes. It's like a sponge. The holes in the sponge are bigger and smaller, which can affect the water stored inside, and the difficulty of extruding the water will change.
The coercive force Hc: the water in the sponge draws the maximum, and then the water pressure comes out and presses it into the sponge. There is no water. The pressure used is like coercive force;Magnetic energy product BH: the water absorption of the sea surface is saturated with the total amount of water inside it.
The residual magnetic Br: compares the magnet to a sponge, and the remanent magnetism is like a sponge absorbing and saturated. At this time, the magnetic value of the magnet is displayed;
