Amplifying range of EMF microphone

Hi! I’m trying to create a sound sculpture that incorporates an EMF microphone (induction coil connected to a male TRS cable). I’m trying to increase the range of the coil so that people can interact with the microphone without having to get too close. The inductor is a Common mode choke,18mH 1A from RS components and it is powered via a TRS cable that runs directly to a Genelec 8040. I have tried to power via a Sound Devices mix pre, however, I found that this only increased the signal output, not the range of the EMF coil. I’m wondering if anybody in this forum could help me figure out whether or not this is possible!

Thanks
