I've just recently got my hands on a Video and put an iFlash Quad in it. I intend to use it as a music source in my car and I normally put my phone on one of those magnetic mounts that you shove in the air vent (like this) so I'd like to do the same with my ipod so it's accessible to replay/skip songs while driving. This in mind, my question is whether it's safe to put the ipod on the magnetic mount without borking the ipod? I know electronics used to be sensitive to this but my knowledge of tech tells me it should be fine now that there isn't a spinning metal disk inside it but I'd prefer to not find out the hard way.

As hinted at in the title, assuming the technology/means existed that could absorb energy fast enough, would it be possible to stop a star from going supernova, effectively "calming" it?

This is for a novel (not exactly a sci-fi one) but I'd like to keep in the realms of "technically possible".

Edit. Thank you to everyone for providing answers and specific thanks to @Solemn@lemmy.dbzer0.com @radix@lemmy.world and @Deestan@lemmy.world for the for the further reading/watching materials that have inspired a narrative solution that is kinda hand-wave-y but should be good enough to hold up to scrutiny until the moment someone with a PhD (or good enough knowledge) takes a closer look at a fictional word with a soft magic system and smashes the big ol' BS button which I think is about as much as fantasy novel writer can ask for.
