Don't know why a customer would care other than curiosity.
That's exactly why you ask the question. Had a similar experience in the Army. The radio antennas on the vehicles always had a label on them warning you not to touch them while transmitting. Our question was "how many volts?" 10 years later, I'm tuning the tubes in a single channel microwave transmitter and my thumb touches an area that shouldn't be touched. The answer to my question was "enough". Enough to transport me thee feet to the floor and 30 seconds into the future. Enough to knock me out cold.
The temp of the coil is also "enough". Enough to burn your flesh. Enough to start a fire. Enough to ignite some flammable gasses. (I can't
vape when doing the acetone finishing on 3D printed parts). So, the moral of the story is to be careful about what you touch.
