No. It cannot be so.

Magnetic loops are no different than any other antenna. As a matter of fact,
about 1/10th wavelength from a small magnetic loop the predominant field is
the ELECTRIC field. So the little thing people call a magnetic antenna
actually has a stronger electric component than magnetic component 50 feet
away on 160 and it remains that way out to perhaps a wavelength, where it
eventually is no different at all than any other antenna.

loop" :

Another common myth is the loop can be shielded from time-varying electric
fields.
