Which of the following statement is correct?
(a) Unit of magnetic field intensity (H) and unit of Magnetization (M) are not same and unit
of Magnetization is A/m
(b) Unit of magnetic field intensity (H) and unit of Magnetization (M) are same and both are
having unit as A/m
(c) Unit of magnetic field intensity (H) and unit of Magnetization (M) are not same and unit
of Magnetization is A/m2
(d) Unit of magnetic field intensity (H) and unit of Magnetization (M) are same and unit of
Magnetic field intensity is A/m2
Solution,
Magnetic field intensity (H) defines the strength of the magnetic field at a point or a place due to a magnet or a current element. It's unit is A/m.
Magnetization (M) is the net magnetic moment per unit volume in a sample. Unit of magnetic moment is Am2. So, unit of Magnetization is Am2/m3 = A/m.
So, the unit of both magnetic field intensity (H) and magnetization (M) are same and is A/m
Hence, the CORRECT option is (B)
Magnetic field intensity (H) defines the strength of the magnetic field at a point or a place due to a magnet or a current element. It's unit is A/m.
Magnetization (M) is the net magnetic moment per unit volume in a sample. Unit of magnetic moment is Am2. So, unit of Magnetization is Am2/m3 = A/m.
So, the unit of both magnetic field intensity (H) and magnetization (M) are same and is A/m
Hence, the CORRECT option is (B)
