Even with Faraday cage, outside in the hallway you could feel the magnet’s pull...People would forget to remove their wallets, and it would erase credit cards..

Lol! I was just about to ask about credit cards.

I wonder how big a shield this could project, how big would it have to be to protect a habitat on Mars? Seems possible.

Here is a must-see NOVA special on magnetism. I’ve seen it a bunch of times over the years. It’s very good.

Actually, I’ve seen it. Good stuff. The question I posed was based on my limited understanding of the shielding effect of Earth’s magnetic field. Can you imagine an Auroral display over a Mars habitat?

Thanks ETL.

You’re welcome. Thanks for “attracting” the list here. :)

I found one of the interesting things in that NOVA special I linked to is the discussion of Mars' magnetic field, and what may have happened to it.

Now, we finally get to magnetars. You may guess from the name that they’re especially magnetic: up to 1 quadrillion gauss. That’s 1,000 trillion times stronger than the magnetic field you’re sitting in right now. That puts magnetars in the No. 1 spot, reigning champions in the universal Strongest Magnetic Field competition.

Too bad John Cameron Swayze isn't available to test this.

Anyone other then me remember that?

And what piece of Americana did it come from?

The Earth’s magnetic field is not even that strong.
from wiki:
“Earth’s magnetic field, also known as the geomagnetic field, is the magnetic field that extends from the Earth’s interior out into space, where it meets the solar wind, a stream of charged particles emanating from the Sun. Its magnitude at the Earth’s surface ranges from 25 to 65 microteslas.”

Gravity is even weaker insofar as a magnet can be used to pick something up from the surface of the planet. Of course, the other two forces are, “the weak force” and “the strong force” which can release nuclear explosions when disturbed.

You can get a couple pretty good magnets from an old hard drive, I have many because we disassemble all our old had drives before disposal.

This guy claims to be the only person that understands magnetism. For what its worth he is entertaining.

Silly Japanese, everybody knows that the best science occurs outdoors and involves fireworks and gasoline.

"Chick Magnet"...

Sorry, that picture showsis a john soliciting a straight-up prostitute. She looks like she is well worth the money though.

For some reason the Japanese have been fascinated by magnetism for 100 years now and have done a lot to advance the state of the art in the field. They invented a lot of the manmade magnets we have today including the common ferrite magnets we see all the time as well as rare earth magnets and the newer super-strong neodymium magnets that are so powerful if you're not careful they can crush you between them and a chunk of metal. Because of this ongoing fascination they were able to miniaturize anything with a motor or generator, which led to big advances in things like autos but also the genesis of the Sony Walkman amongst other things. I've seen them use neodymium magnets to create a cooling effect (metal that gets closer goes up in temp slightly) that powers super efficient refredigerators and/or air conditioners. But the stronger the magnet, the more efficient the refridgeration. Becuse of things like this they want stronger and stronger ones all the time.

Not surprising to see yet another such breakthrough coming from Japan.

During basic training back in the old days I was selected to help set up the pyrotechnics for the night training and the old sarge put a gallon of gasoline on top of the dynamite we placed in the holes on the obstacle course. More fun.......

One of my buddy’s who is a gifted electronics engineer with a photographic memory always bitch’s at me “I don’t understand your obsession with time” LOL

I’m like “dude, you need to stop listening to the grateful dead” :)
