Magnet Release

is a combined nature transformation kekkei genkai  being made up of techniques that mix wind and earth-based chakra to create magnetic forces in different properties and usages. Various shinobi of Sunagakure, Kumogakure and Ishigakure have possessed this kekkei genkai.

Forms

 * Shukaku uses Magnet Release in conjunction with the cursed seal markings on his body. Naruto Uzumaki was able to incorporate these powers into his Rasengan to create the Sage Art: Magnet Release Rasengan, which has the additional effect of binding a target when struck.
 * The Third Kazekage studied the abilities of one of Shukaku's jinchūriki and imitated their sand control by manipulating Iron Sand with his magnetic powers. He would use the iron sand to crush his opponents, or mould it into weapons. In Gaara Hiden: A Sandstorm Mirage, Kajūra, a terrorist from Ishigakure, can also use Iron Sand, while in Boruto: Naruto Next Generations, it is shown that Shinki is capable of manipulating it as well.
 * Rasa from Sunagakure could manipulate Gold Dust with his magnetic powers, which is specifically used to counter Shukaku's sand, taking advantage of gold's heavier weight by mixing it in with the sand to hamper its control. When Rasa uses this nature, he gains black rings around his eyes, similar to the ones around Gaara's eyes.
 * Toroi from Kumogakure would magnetise special shuriken. When the thrown shuriken comes into contact with any other object, it causes the struck target to become magnetised. One hit to the body will create a magnetic field within said body, making it an easy target for any further magnetised weapons to be drawn to it. However, each time the magnetism is transferred, it weakens.
 * In Gaara Hiden: A Sandstorm Mirage, it is stated that Gaara inherited Rasa's Magnet Release. Instead of Gold Dust however, he manipulates a "sparkling metallic sand" of high density, which was able to counter techniques that were specifically designed to defeat Gaara's sand defences. He could even use the substance as a variant or mix it together with his absolute defence.

Trivia

 * Like Lava Release, Dust Release and Explosion Release, Magnet Release has more than one user with no apparent blood-relation to each other.
 * The anime-exclusive character Jiga also possessed a seemingly similar ability of magnetism. This was from ingesting iron when he was younger which essentially made him a human magnet.
 * This is so far the only nature transformation that does not use the element for direct offence. Instead, all the users so far use it to manipulate weapons to attack as the chakra is converted into magnetic forces, rather than metal itself.
 * The magnetisation of Gold Dust and manifestation of rings around the eyes by the Fourth Kazekage may indicate a diamagnetic strain of Magnet Release that magnetises inherently non-magnetic materials like gold and sand.
 * In Japanese folklore, tanuki are widely known for their ringed eyes. Shukaku is such a creature.
 * Though originally attributed to his insomnia, Gaara's ringed eyes are possibly the result of his being in constant effect.
