What are the units for magnetic field?
Usually, magnetic field strength is defined by the unit of Oe・A/m ( Oersted・Ampere/meter ). And when it is defined by flux density, the units of G (Gauss) or T (Tesla) are used.
What is magnetic intensity H?
The ability of a magnetic field to magnetize a material medium is called its magnetic intensity H. Its magnitude is measured by the number of ampere-turns flowing round unit length of a solenoid, required to produce that magnetic field. unit of H is ampere-turns per meter (Am⁻¹).
Is magnetic field B or H?
B is the magnetic flux density and is unique to the material. Higher μc means more magnetic flux density under the same magnetic field. H is the magnetic field strength and is an absolute quantity.
What is the difference between B and H in magnetism?
B is magnetic flux density, whereas H is magnetic field intensity.

What is B and H in BH curve?
B-H curve is used to show the relationship between magnetic flux density (B) and magnetic field strength (H) for a particular material. When tested experimentally, a ferromagnetic (i.e. strongly magnetic) material such as iron will produce a curve similar to that shown above.
What is H-field called?
The H-field is the vacuum permeability, and M is the magnetization vector. In a vacuum, B and H are proportional to each other. Inside a material they are different (see H and B inside and outside magnetic materials). The H-field is measured in amperes per metre (A/m) in SI units, and in oersteds (Oe) in cgs units.
What is H-field and E field?
The electric (E) field is much like the electric voltage potential (E) of an electric circuit. The magnetic (H) field is much like the electric current (I) of an electric circuit. NOTE: In this text, the symbol “E” usually refers to the electric field component of an EM field.
What are H fields?
The H-field is a vector quantity (has a magnitude and direction) and is measured in Amps/Meter [A/m]. Recall that the E-field points away from a positive point charge. An H-field curls (or wraps) around a wire of moving charge, as shown in Figure 1. Hence, H-fields are associated with moving electric charges.
What is the SI unit for the magnetizing field H?
The tesla (symbol T) is the derived SI unit of magnetic flux density, which represents the strength of a magnetic field. One tesla represents one weber per square meter.
How do you calculate H from BH curve?
The relationship between B and H is B=μH. So if you have a B-H curve for a given material, you can find your permeability, μ, by finding B divided by H. Keep in mind that permeability is a function of H, it is not constant for all values of H.
