Anyone up for a little science?

Asked by HarryPotterFreak (163points) April 30th, 2012

Is it possible for magnets to work on planets without a magnetic field? I’m pretty sure that it is; but, what do you guys think?

Of course. Magnets have their own magnetic field.

AC magnets or DC magnets? If AC magnets, 60Hz or 400Hz? Three phase magnets?

Magnets work because they are made of magnetic material that has been polarized. It does not matter where they are located.

Now if you mean magnetic compasses, it will depend on whether the planet has a polarized metallic core.

You didn’t provide enough information. Temperature and pressure are important factors to consider. I think that a magnet on a planet with a temperature on or about absolute zero (0 degrees Kelvin) would not function. Also if the temperature was that of the melting point of iron you would have a very poor functioning magnet.

What if the planet was falling into the colossal forces of the singularity of a black hole where light cannot escape?

Go back and review.

What a magnet won’t do, however, is align with the planet’s magnetic field like compasses do on Earth.

@Rarebear – you mean: a magnet will not align with that planet’s axis, since it did not have a magnetic field.

@RocketGuy No, I meant what I said. The magnetic field doesn’t have to be aligned with the axis. It’s not on Earth.
