Soulcasting and Magnetism

[+Invocation]

How does Soulcasting work with magnetism? Would you be able to Soulcast something into a magnetic thing?

[Gasper he/him]

Yes, I do not see a problem with this. In fact you see this happen when the armor in the visions is soulcast iron.

[Quantus he/him]

Sure, you'd just need to know enough about the material to have the Intent to align the molecules when you create it. Probably would happen automatically with naturally magnetic minerals, since you'd know it as a intrinsic property you might not need to fully understand the crystalline structure that causes it.

I would speculate that a skilled soulcaster should be able to command ferromagnetic objects to realign their atoms to create exceptionally powerful magnets. For steel and iron I would think this could be done with relatively little technical knowledge; if they have Maxwell's laws and a semester of thermodynamics they should be good to go.

On the plus side, just off the cuff this should probably require 1-3 orders of magnitude less Investiture than a complete material change, as long as they weren't trying to make a magnet so strong that it exceeded the theoretical limits of the material.

Good point on energy efficiency

Im trying to think offhand, do we know any Surge mechanisms (other than roundabout Soulcasting methods) that can directly create electric current?  Anything that can create a reasonably cinematic lightning effect is going to be able to deliver the sorts of high-current bursts of electricity you need for magnetizing iron.  My old mentor once built one of those giant scrapyard magnets (but was moving finished sheets iirc) to work that way where you used the burst to toggle the magnetism on and off in the material rather than maintaining it electrically.

Allick uses a grain of etmetal to power mechanisms that, to me, sounded a lot like fluorescent tubes, to light up the temple of the Sovereign. Not conclusive, but my impression is that the Southern Scadrians are probably (among other things) using Imvestiture to create a potential difference and thereby induce current flow by mechanizing feruchemy and/or allomancy.
