Typical frequencies for devices generating intermediate frequency fields

Intermediate frequency fields 300 Hz - 100 kHz
Anti-theft devices Ranging from some tens of Hz to a few GHz depending on the type of system
Induction hobs and hotplates 20 to 50 kHz
Electric engines and badge readers About 100 kHz
Radio transmitters operated in the long wave range 30 kHz to 300 kHz
Welding devices Up to a few 100 kHz
Induction heaters Some tens of Hz to some tens of kHz
Electrosurgery systems Some hundred kHz
Clinical MRI devices use intermediate frequency fields in addition to static and radio frequency fields Up to 10 kHz
