No, but current causes the H-field.

An antenna loading coil has volts and amps from both directions in a
standing-wave antenna. These two waves create the standing-wave pattern
seen along the antenna`s length (including the coil).

The coil has a finite length so the sum of the forward and reflected
waves make volts, amps, and impedances which vary from coil end to coil
end,
