WebThe gauss meters available from ARPANSA measure magnetic fields from electrical sources that operate in the frequencies between 25 Hz (40 Hz for the EMDEX Snap) to 1000 Hz in units of mG. The magnetic field meter is not suitable for the measurement of radiofrequency fields emitted from telecommunications sources such as mobile phones, … WebWhere ϕ = force producing the field, ℛ = resistance to the magnetic flux (reluctance). The relationship between F in gilberts and ampere-turns is a factor of 1.257. This relationship is stated: F = 1.257I ×N F = 1.257 I × N. Where F is the force in gilberts, I is the electric current, and N is the number of turns. hillcrest strategic partners

"When an EM field (see electromagnetic tensor) is not varying in time, it may be seen as a purely electrical field or a purely magnetic field, or a mixture of both. However the general case of a static EM field with both electric and magnetic components present, is the case that appears to most observers. Observers who see only an electric or magnetic field component of a static EM field, have the other (electric or magnetic) component suppressed, due to the special case of the imm… " - How is current related to magnetic field
