The Chargestone Cave is originally inaccessible in Black & White until Clay opens it up for you. This cave has strange electromagnetic properties and has numerous puzzles which have you pushing rocks to get magnetised and pulled to the larger rocks. Team Plasma have a presence here in the first visit of Black & White.
Due to the special electromagnetic properties of this cave, if you level up a Magneton or Probopass within the confines of the cave, they will be able to evolve.
