What Is Magnetic Flux Density?

Saturated magnetic flux density refers to the phenomenon that the current used for magnetic flux density increases to a point, but the magnetic flux of the iron core does not increase.

Saturation magnetic flux density

Right!

Saturated magnetic flux density refers to the phenomenon that the current used to increase the magnetic flux density to a point without increasing the magnetic flux of the core.

Saturation causes the magnetizing current to increase and the core to heat up.
