You didn¹t cite frequency range specifically and I¹m not familiar with frequency range of the specificaiton citation. A standard for 30 Hz to 100 kHz is a 13.3 cm diameter model with 36 turns of wire. Developed iaw MIL-STD-462. Another covering the same range developed later for the same spec is even smaller in diameter. As John Woodgate noted, there are some magnetic field probes made by ETS Lindgren and others developed as troubleshooting probes. These have various smaller diameters and varying number of turns, and the calibration factor is simply calculated based on the area and number of turns (Faraday Law calculation).
