What is the difference between magnetic field strength, magnetic field intansity and magnetic flux density. I have heard that MG intansity is independent of medium it represents the magnetizing power of a magnetic force

>Biot Savart law gives us magnetic field strength or magnetic flux density?​


Biot Savart Law is expressed by B or H. It is difficult to say the law is specially designed for B or H.
H is partial field of B [tex]\mathbf{H}=\frac{\mathbf{B}}{\mu_0}-\mathbf{M}[/tex] In magnetic material media behavior of B and H differ. In vaccum B and H differ only by constant 1.25663706 × 10-6 m kg s-2 A-2.
