Physicists from the Institute for Solid State Physics at the University of Tokyo, Japan, have recorded the largest magnetic field ever generated indoors a whopping 1,200 T (tesla)
Magnetic fields are one of the fundamental properties of a physical environment, said lead author Dr. Daisuke Nakamura and colleagues.
They can be controlled with high precision and interact directly with electronic orbitals and spins; this makes them indispensable for research in areas of solid state physics such as magnetic materials, superconductors, semiconductors, strongly correlated electron materials, and other nanomaterials.
The researchers generated ultrahigh magnetic fields using the electromagnetic flux-compression (EMFC) technique.
We developed a high performance EMFC instrument to generate a megagauss magnetic field, they said.
The conversion efficiency of the electric energy stored in condenser banks to the imploding liner kinetic energy was found to be substantially improved in comparison to those in previous instruments.
The magnetic field was measured by the reflection-type Faraday rotation probe using an optical fiber, and a peak field of 1,200 T was recorded.
By comparison, this is a field strength about 400 times higher than those generated by the huge, powerful magnets used in modern hospital MRI machines, and it is about 50 million times stronger than the Earths own magnetic field.
Stronger magnetic fields have previously been achieved in outdoor experiments using chemical explosives, but this is a world record for magnetic fields generated indoors in a controlled manner.
That greater control means the discovery could open new frontiers in solid-state physics, perhaps allowing scientists to reach what is known as the quantum limit, a condition where all the electrons in a material are confined to the lowest ground state, where exotic quantum phenomena may appear.
This work opens up a new scientific horizon and has pushed the envelope for ultrahigh magnetic fields, Dr. Nakamura said.

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?
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.

Too bad John Cameron Swayze isn't available to test this.
“He who controls magnetism controls the universe” - Diet Smuth!
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.
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.
Sorry, that picture showsis a john soliciting a straight-up prostitute. She looks like she is well worth the money though.
Not surprising to see yet another such breakthrough coming from Japan.
Or Mr Peabody, Sherman! Set the Wayback Machine!
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” :)
