The thoughts and feelings of two dancers, pulled together almost like a magnet, are vividly relayed in this duet featuring Miku and Luka. The visuals are realized with a classical Japanese motif.
— Website description
"magnet" first appeared in Hatsune Miku: Project DIVA 2nd where it was available at the start of the game. It was also available in Hatsune Miku: Project DIVA Dreamy Theater 2nd with the exact same rhythm game and PV (albeit with updated high-definition visuals). "magnet" is also featured in Hatsune Miku: Project DIVA Arcade where it was added to the game on 4 August 2011. When the arcade game was updated to Hatsune Miku: Project DIVA Arcade Future Tone, an Extra Extreme difficulty rhythm game chart for the song was added on 25 October 2017.
The song was later featured in Miku Flick/02. It also appears in Hatsune Miku: Project DIVA F 2nd, where it was one of the game's DLC that can be purchased from the PlayStation Store. Its PV was based from its earlier appearances but was slightly modified to include a Chance Time Success event. In Hatsune Miku: Project DIVA Future Tone, "magnet" was included in the Future Sound song pack and its Extra Extreme difficulty chart was added later via a patch on 19 April 2018.
