Some caution is in order as some ferrites used in RF transformer coils may be permanently altered by application of a strong magnetic filed. Testing at lower fields first would be safer. Setupo a pair of Helmholtz coils and excite them with low frequency AC and look for associated sidebands in the oscillator output. NB a spectrum analyser is unlikely to be sensitive enough for this.
I was just about to say the same. Also, it has much higher repeatability and makes quality measures on measures and counter-measures much easier to achieve.
