The wires are not manipulated by the supernatural, Accelerator's tosses are just the object's natural reaction to getting hit really hard (just like how Saints can throw objects at supersonic speeds), and only the collection part of Marian's weapon is done using supernatural means. If it was shot with a supernatural force behind it, then it will be negated. But it only leaves the sphere because of differences in pressure.
The entire force behind the coin in Mikoto's railgun is the Lorentz force. It's similar to how vibrating iron sand (object manipulated by the supernatural) swords don't keep vibrating and remain deadly once struck by IB. Or how Sherry's earth (object manipulated by the supernatural) golem doesn't continue punching and just stops. Or how the distortion in space (object manipulated by the supernatural) caused by teleportation is removed once IB touches it.
This is not just an issue of yes or no. You need to ask "how" it is being manipulated.
