An electromagnetic coil assembly for inducing electromagnetic fields in a head region of a treated subject, the coil assembly comprising a plurality of windings configured to define an applicatory coil portion configured for placement in close proximity to the head of the treated subject to induce the electromagnetic fields, and an elevated coil portion passing relatively remote from the head of the treated subject and configured such that electromagnetic fields thereby produced are generated substantially remote from the head of the treated subject to prevent them from interfering with the electromagnetic fields generated by the applicatory portion of the coil, thereby allowing directing the electromagnetic fields generated by the applicatory coil portion substantially accurately to desired inner regions of the head of the treated subject. A support structure is used to enclose and immobilize at least a portion of the windings of the coil, while enabling elastic movement of other portions of the windings that are not held by the support structure, to thereby enable size adjustment of the coil to fit over a region of a head of the treated subject.
