UnitsmA/m,dBL
The magnetic eld strength is measured in A/m (Ampere per meter).
AFIL systems use 400mA/m as a reference level. The logarithmic unit
of the magnetic eld strength is dBL (dB Loop) and has a reference
level of 400mA/m.

The designator of the unit dBL is not standardized jet - but resulted
of IEC 60118 committee members recommendations.
