A head covering garment is configured to administer electromagnetic therapy to treat a cancerous tumor within a brain. The head covering garment includes a crown, which contains within its walls at least two magnetic coils (also referred to herein as solenoid coils). Each solenoid coil is energized, when in therapeutic operation, with a distinct time-domain signal. The time-domain signal consists of a series of summed sinusoidal waves from a power supply. The coils are oriented within the wall of the solenoid assembly such that for any two coils a first magnetic coil and a second magnetic coil are oriented relative to each other so as to be nonparallel. The purpose of having two distinct coils is to focus resultant magnetic fields such that at a tumor site within the brain encloses to form a local maximum formed by superposition within the cancerous tumor.
