Neodymium magnets have an energy capacity of 512 kJ/m3 or 0,512 MJ / cubic liters.
That's equivalent to 0.0085 kWh or 8.5 Wh each 1 dm^3.
You could recharge an mp3 player for 34 hours, and then you'd have to throw away your magnet.
That's still 468 times less than the capacity of a Lead-acid battery.
Do you think a Neodymium magnet is a good energy storage?
Even though a lead acid battery is 468 times more powerful than a neodymium magnet,
doesn't mean it can deliver 3978 W (power a whole house) for an hour at the size of your milk carton. That's probably too much current drawn from a battery, which would lead to an explosion.
Trying to draw that much energy from a magnet is probably even harder.
