Getting E-Field from magnetic field intensity, H - Physics Forums
Jun 3, 2008 · The E-field and magnetic field intensity, H, are both components of an electromagnetic wave. They are perpendicular to each other and together they create an electromagnetic field. The strength of the E-field is directly proportional to the strength of the H-field, as shown in the equation E = cH.
Relation Between the Magnetic Field Strength and Distance
Oct 5, 2013 · The strength of a magnetic field is inversely proportional to the distance from the source of the field. This means that as the distance increases, the strength of the magnetic field decreases. How does the strength of a magnetic field change with distance? The strength of a magnetic field follows an inverse square law.
