No, electrostatic forces are usually weaker than magnetic forces, but they're not negligible and you can build generators and motors that work electrostatically.Permanent magnets take energy to create; it's not possible to make them with no energy, but they do generally persist for very long periods.
The equivalent with electrostatics is called an electret:
and can store a very long lasting electrostatic charge. You can shape electrostatics with a metallic surface, to form an equipotential of arbitrary shape.
What forces can electrets generate? Similar to strongest permanent magnets?
Also, if get close to another electrostatically charge, what will happen? Will they lose their electrical properties?No, they're fairly stable. I'm sure you can erase the charge in a powerful enough electric field, or by overheating them, but in normal use you won't.
I don't think so, or not significantly, it's just more difficult to mobilise. You can mobilise it with solvents or even oils. Lycopene is actually a solid, and in tomato sauce it's presumably dissolved in the small amounts of fats and oils naturally in the tomato, and they would soak into the fabric, so detergents help as well. Lycopene is also broken down by UV, so leaving it out in the sun helps.so tends to soak in and stay in fabrics
So is it binding to non-polar moieties in the chemicals that make up the fabric? Like the cotton fibres, for instance?
