King Slag Iron Magnetic Field Intensity

What is magnetic field strength Definition from

Magnetic field strength is one of two ways that the intensity of a magnetic field can be expressed Technically a distinction is made between magnetic field strength H measured in amperes per meter A/m and magnetic flux density B measured in Newton meters per ampere Nm/A also called teslas T The magnetic field can be visualized as magnetic field lines
