New device invisible to magnetic fields

DC magnetic fields are used in MRI imaging devices, in hospitals and in security systems, such as those in airports.

Placed in a magnetic field, the device has no effect on the field lines, showing neither a shadow nor a reflection. So an object inside the device cannot be detected.

Hmm.

You have a good eye, Tigerseye

That’s the way of technology though isn’t it? Whatever the latest defensive or offensive gizmo is it is never very long before something is made to defeat it. But the productive uses are good.

[SatinDoll]

What effect would this device have on nearby electronic equipment during an EMP attack? Any guesses?

[TXnMA]

Not good for trying to sneak something past security, if that is what you are thinking. Even if you could make it portable and concealable under clothing, the LN2-cooled superconductor section would be obvious to an IR scan...

[TigersEye]

You just had to go an ruin that didn't you?

Here I am all dressed up with my LN2-cooled superconductor section under my overcoat and nowhere to go. ;^)

Would this be a “cloaking device” (as in Star Trek)?

Invisibility is a state of mind....been there a few times.

It sure sounds like it.

It sounds like only cloaking to magnetic field reading devices. Obviously not to visible light (but I think someone has come up with that to a degree?), but to magnetic sensors. I’m not sure about electromagnetic sensors - but I am guessing that it is. I would imagine that the stuff at the airports is electromagnetic (to detect all metals) and not just magnetic (iron only).

Better have your woolies between the device and your skin!

[TigersEye]

I made a shirt with a space blanket. ;^)

Save your money. Recent reports are showing that a weapon concealed on the side of your body gets lost in the background shadow of those newfangled airport security scanners.

Yeah. Tequila induces that...

[Right Wing Assault]

Just put it inside the box.

Box better have some VERY good insulation or your are going to have major problems.
