Magnet Release can manipulate Iron Sand, and Gold Sand, this pattern suggests that Sand can also be manipulated. Gaara's Magnet Release could be inherited from Rasa, which also explains why Shinki has Magnet Release. Not saying that Gaara's Magnet Release isn't influenced by Shukaku though. Shukaku's Magnet Release is used to manipulate sand, or even his body, because technically his body is "Magnet Release", just like how Matatabi's body is "Fire Release".
