What are sources/equipment's generating Alternating Magnetic field at high frequency (300 - 500 kHz)?

12 December 2019 1 5K Report

A nano-composite material (polymer doped with Magnetic Nanoparticles), just need to be tested to study for any heat generation in the presence of alternating magnetic field only. For that purpose trying to find, What are the sources/equipment's generating Alternating Magnetic field at frequency (300 - 500 kHz)? As ideally no spectra or computer software is required in the mentioned research work, I mean we can test our samples response in other way but just need the Alternating Magnetic field at frequency (300 - 500 kHz)?
