What is the formula for magnetic field intensity?
The Magnetic Field Intensity or Magnetic Field Strength is a ratio of the MMF needed to create a certain Flux Density (B) within a particular material per unit length of that material.
H = At/m, ampere-turns per meter.
Often, N is used as the number of turns of wire around a core or magnetic material.
So the H = N*I/m..
What is the difference between magnetic field and magnetic field intensity?
Magnetic field strength, also called magnetic intensity or magnetic field intensity, the part of the magnetic field in a material that arises from an external current and is not intrinsic to the material itself. It is expressed as the vector H and is measured in units of amperes per metre.
What is meant by magnetic field strength?
A vector quantity indicating the ability of a magnetic field to exert a force on moving electric charges. It is equal to the magnetic flux density divided by the magnetic permeability of the space where the field exists. It is measured in amperes per meter. Also called magnetic intensity.
What is a magnetic field and where is it the strongest?
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
What is the difference between H and B magnetic fields?
In summary different units but the same in a vacuum. In a material with a magnetization B type magnets of magnetic field lines that are solenoidal while H have irrotational field lines.
What do magnetic fields do?
Magnetic fields are areas where an object exhibits a magnetic influence. The fields affect neighboring objects along things called magnetic field lines. A magnetic object can attract or push away another magnetic object. You also need to remember that magnetic forces are NOT related to gravity.
