Patent ID: 8888673

Claim:
A device for applying a magnetic field to a head of a subject comprising: a first permanent magnet within a container; a second permanent magnet within the container; the container comprising a concave treatment surface configured to fit the head of the subject, the concave treatment surface comprising: a first portion configured to be between the first permanent magnet and a first nearest portion of the head of the subject; and a second portion configured to be between the second permanent magnet and a second nearest portion of the head of the subject; and a subunit coupled to the first and second permanent magnets comprising circuitry programmed to move said first permanent magnet and said second permanent magnet at a frequency in a specified EEG band which is greater than about 1 Hz thereby generating the magnetic field; wherein the device is effective at applying the magnetic field to the head of the subject when there is a first distance between the first permanent magnet and the head of the subject measured through the first portion of the treatment surface that is about 1/16 inches to about 5 inches and there is a second distance between the second permanent magnet and the head of the subject measured through the second portion of the treatment surface that is about 1/16 inches to about 5 inches.
