1. A wind turbine blade, extending in a longitudinal direction between a root end and a tip end, comprising:
a shell having an outer surface defining a pressure surface and a suction surface, a leading edge and a trailing edge;
a load-bearing structure extending in the longitudinal direction;
a peripheral device magnetically coupled to a portion of the outer surface of the blade via a magnetic coupling; and
the magnetic coupling comprising a first element formed in the shell beneath the outer surface such that the outer surface overlies the first element.
