  • Relation between the magnetic field vector vec(B) and magnetic intensity vec(H) at a point in a magnetic field vec(B)=muvec(H) where mu is the magnetic permeability of the medium in which the point is situated . Magnetic permeability of vacuum mu_(0)=4pixx10^(-7)H.m^(-1) . Thus the relative magnetic permeability of the medium mu_(r)=(mu)/(mu_(0)) . To define the magnetic field at a point in a medium another vector needs mention , which is magnetisation vec(M) . The magnetic field is known as the magnetisation of the point . In most cases vec(M)propvec(H) " or, "vec(M)=kvec(H), this k is called the magnetic susceptibility of the medium . The relation among these vectors is expressed as vec(B)=mu_(0)(vec(H)+vec(M)) . Magnetic permeability at a point in the medium is 0.002H.m^(-1) . The magnetic susceptibility of the medium is

    A
    `-0.03`
    B
    `-0.003`
    C
    `0.03`
    D
    `0.003`
