Microwave oven EM wave amplitude

Click For Summary
SUMMARY

The amplitude of electromagnetic (EM) waves generated by microwave ovens is typically measured in electric field strength units, specifically dBuV/m, rather than in tesla, which is used for magnetic field strength. In the context of microwave ovens, the focus is on the electric field component of the EM waves, as these devices operate primarily as RF transmitters. Understanding the distinction between these measurement units is crucial for accurately quantifying the performance and safety of microwave ovens.

I don't really know how to quantify EM waves when it comes to amplitude, but I understand that MRI rf waves are measured in units of tesla. What is the amplitude of a typical microwave oven EM wave in Tesla (mT, uT)??
 
Physics news on Phys.org
Tesla is the measurement of a magnetic field strength ( more precisely, magnetic flux density)

Whereas a RF transmitter like a microwave oven ( or any other transmitter), it would normally be the electric field
strength that is measured and that is usually in dBuV/m

Others may expand on that :)
