Head-mountable adjustable devices for generating magnetic fields

A system, comprising:

• a device comprising:
• a housing operable to receive at least a portion of a head of a subject, wherein the housing is reversibly transformable between a closed configuration and an open configuration;
• a magnet assembly within the housing comprising:
• a first permanent magnet, a second permanent magnet, and a third permanent magnet;
• and
• a first fit mechanism comprising a first adjuster coupled to the first permanent magnet, wherein movement of the first adjuster moves the first permanent magnet independently of one or more of the second permanent magnet and the third permanent magnet, relative to the housing, and wherein the first adjuster extends outside of the housing when the housing is in the closed configuration such that the first adjuster is operable to be accessible to one or more of a user and the subject when the housing is positioned on the head of the subject;
• and
• a controller comprising a processor and non-transitory computer readable media, wherein the processor is operable to execute an instruction to control the first fit mechanism of the device using one or more of a wired connection and a wireless connection.
