Why do we have/need 3 different readings?

I thought Electro-Magnetic waves / fields were always including a Magnetic part related to the Electric part (and the other way round also).

Instead we have 3 different measures the EF part, the MF part (called "EMF") and yet another one, the "RF" part. Why are these 3 unrelated things?

Do these 3 cover different frequencies/parts of the RF spectrum?

Thanks.

Generally, EMF is for lower frequencies up to 400kHz for EMF360/+/380/+/390 and RF is for higher frequencies.
EMF and EF are completely different things. EMF is for magnetic field generated by electricity. While electric field exists everywhere where there is charge/potential electric energy.

OK, I think I understand your explanation about EMF and EF not being related.

However Your first sentence is not clear to me:

> Generally, EMF is for lower frequencies and RF is for higher frequencies.

Is RF, the "high frequency version" of EMF or the "high frequency version" of EF ?

Thanks.
