About These Units
Oersted (Oe)
The oersted (Oe) is the CGS unit of magnetic field intensity (H-field), not flux density (B-field). In vacuum/air, 1 Oe ≈ 79.58 A/m. Related to gauss through permeability: B(G) = μ × H(Oe). Named after Hans Christian Ørsted.
Femtotesla (fT)
A femtotesla (fT) equals 10⁻¹⁵ teslas. Measures biomagnetic fields: human brain activity 10-1000 fT, human heart (MCG) 1-100 pT. SQUID sensors can detect sub-femtotesla fields. At the frontier of magnetic field measurement.
