Do you think magnetism can be used as an effective means of storing energy? I mean like use renewable energy to generate a magnetic field and use that to lift a metal mass, for example.

Magnets dont produce any work

Without power the metal will fall.

Then the energy is just stored as gravitational potential energy. One can do this by pumping water up a dam or driving an electric train up a hill. For the dam we can get power out again by letting the water downhill through a turbine connected to a generator. For the train we regeneratively brake as we go down hill.
If we really want to store electricity in a magnetic field we can dump a huge current into a superconducting cable loop

Sure, you could arrange a linear motor vertically and use it to raise a mass, then generate power on the way down.
However, a standard motor attached to a winch is much more efficient.

Energy is stored in the magnetic field via inductors.

I thought this was going to be a thread about "charging" a material with magnetism so that it becomes a magnet on its own and can then be used for years just like a normal magnet.
No, it is just an electromagnet thread and the OP doesn't know how that works.
On a side note, is anyone trying to make artificial magnets that are not just an electromagnet and not just metal that's been exposed to another magnet?

Aren't those really only good for switching purposes for power grid stability? Much like those flywheels used for server farms but cleaner?
The magnetic field created by an inductor is technically energy storage

What?

This thread is made of ass and poo, but can we take a moment to acknowledge how fucking awesome tardigrades are?
