I was wondering what that typical hi pitched whine is that usually is used to represent magnetism? I'm looking to make a metal object sound as if its being drawn to another larger one. Any ideas would be most graciously appreciated. Thanks!

    Perhaps a low frequency layer fading in as the objects close...? Aug 21, 2015 at 12:06

Lots of different examples of this in cinema, not all involving "hi pitched whines". If I were trying to convey magnetism I may try the opposite first (low energy) or elements of vibration (think hematite magnets rapidly coming together in a spinning motion). There are endless ways to approach what you are doing, and as usual it all depends solely on the context of your unique project. Cool question, though!

    Hey thanks Jay, yeah under the high pitched whines for the bolts moving I have a low pitched FM sine wave with Enigma on it to add some pulsing warble to it. I think it help give the impression the plate is magnetic and drawing the bolts to it. Aug 21, 2015 at 9:42

I think what feels right will depend on the size and shape of the magnetised objects. For example I remember creating a loop for a magnet pulling which focused more on the sounds of metal groaning and bending rather than anything abstract.

Perhaps if you are wanting a more drone like sound though you could use source material with metallic textures to link it with the object.... a thought anyway.
