Magnetism

Magnetism is the electric force that attracts two metals to each other, and a secondary element. It is manipulated by Gahlok-Kal or a Toa of Magnetism such as Jovan.

Examples
Creating two magnets around an object to break it.
 * Increasing and/or decreasing the magnetic field in an area.
 * Shooting beams of magnetism.
 * Generally influencing a certain target's magnetic properties.
 * Manipulating metal via magnetism.
 * Unleashing an enormous blast of magnetism known as a "Nova Blast".

Elemental Position
Magnetism is strong against Iron but weak against Sonics

Combinations
It has been confirmed by Greg Farshtey that beings other than Toa cannot combine powers of any sort to create a Protodermis cage. It has also been confirmed that as long as each wields a different element, any six Toa can create a Protodermic cage.
