Morpheus: Let me tell you why you're here. You're here because you know something. What you know you can't explain, but you feel it. You've felt it your entire life, that there's something wrong with the world. You don't know what it is, but it's there, like a splinter in your mind, driving you mad.

The most popular Resource Page that I've written for Circuit Cellar Online, by far as been the one I wrote about Magnets.

In that paper I pointed to a table from a government site that explained the magnetic units.  Before my Magnet Resource Page saw the light of day on Chip Center, the government redid their site.  If it is still there I can't find it.  Because I've been burned this way in the past, I've learned to snag a copy of the Interesting Stuff  before it disappears from Cyber Space.

Here is the important tables from my article on Hall Effect Sensors that I saved as well.  Several people have asked for them.

Magnetic Units -- Confused by magnetic units? Most people are! Download this carefully done table of the units from the Electromagnetic Technology Division of  Electronic and Electronic Engineering Laboratory of the National Institute of Standards and Technology.

WARNING:  Some magnets are so strong that they present serious hazards of one type or other.  Such as pinched or crushed fingers, freezing hazards from cryogenics, or potential health effects the causes of which are still unclear or unknown.  Also some magnets are prone to shattering.  You are the person most responsible for your own safety.

'Electrosmog' is a term used to designate artificially generated electromagnetic pollution, meaning electric (E) fields and magnetic (H) fields.

Such fields arise wherever there is a voltage or a current. All types of radio broadcasting and TV transmitters produce electromagnetic fields, and they also arise in industry, business and the home, where they affect us even if our sense organs perceive nothing.

Unit of electric field strength: Volts per meter (V/m).
Units of magnetic field strength: Amperes per meter (A/m) or magnetic flux density (B) in Tesla (T) or Gauss (G).

What do you know of Magnetic Impedance Sensors? This is all I know: AICHI DEVELOPS TERRESTRIAL MAGNETIC SENSOR FOR LOCATION INFO FOR MOBILE PHONES.

Wonder what amphorous alloy is required and where 20um diameter wires can be gotten in small lengths for tests- probably some dept. of Aichi, if at all? It does seem like a normally small effect, you don't usually notice it in any wires, but they claim it is a million x more sensitive than Hall sensors!

If hyperspace navigators get paid by the hour, then what is the pay-scale in a place where time has no meaning?
