"RF" refers to the frequency, not the nature of the field.
When you apply AC voltage to a capacitor, or current to an inductor, you get an oscillating electric or magnetic field inside the capacitor or inductor.
This is the difference between "near field" (where energy is stored in oscillating EM fields, near the antenna/coil structure) and "far field" (where energy propagates away from the antenna/coil structure, i.e., radiation).
The details of this are complicated, but the concept is essential to understanding EM radiation and antennas.
For example, medical MRI does not use "radio waves", but oscillating magnetic fields inside the scanner.
Similarly, when you hold a cell phone against your head, your body is in the near field of the phone, and the regulations limit the "SAR" (specific absorption rate) in W/kg from that field.
However, when you stand several wavelengths away from a cell tower, your body is in the far field of the antenna, and the relevant parameter is the radiation field strength (V/m).
