I just seen the Spiderman 2 movie and
*SPOILER ALERT!*
Gwen tells Peter to magnetize his webshooters so they won't be damaged by electro's lightning, since his webs seems to conduct electricity.
Now, the explanation is that a magnetized object can hold electric charges. How is that? Also they magnetize it using a car battery.
What i now from electromagnetism is that a ferromagnectic material can be magnetize if exposed to a very very strong magnetic field that will align the material domains and make it work like a magnet. This can be made with a strong electromagnet, which i believe can't be made from a car battery..
But that's not the problem, since it's only a movie we expect things like that. My question is how does magnetizing a material makes it "hold electric charge" and how does this makes it imune to electricity? I know that in real life things doesn't work this way, but they should at least embase their facts in something real.
