Survival Praxis #33 – Measuring the Earth’s Magnetic Field for Dummies (I’m the Dummy): A Calibration Method

Ley Lines

If while playing with a magnet, you attach it to the underneath side of a coffee table and then toss small metal shavings on the topside, the shavings will tend to organize themselves into a pattern. The pattern will follow the paths of attraction and form toroidal shaped lines from pole to pole. These apple-shaped lines represent the magnetic field of the magnet.

The magnetic field operates more like a net or web in which these lines of force represent concentrated strength, while farther away in the empty space in between, the influence is diminished until the object reaches the range of control of the next field line. Some scholars call the lines of Earth’s magnetic field “ley lines.”

The dynamo of an electric motor works by spinning such a grounding object to interrupt these lines of force and create a short in the circuit, or the spark, which forms an electric current.

[Side Note #1: In an earlier survival praxis, we called the planet Mercury a “cue ball” because it controls the Sun’s magnetic fields which are essential to its nuclear and thermonuclear process. McCanney calls Mercury the Sun’s “spark plug,” probably a better analogy. Because the planet is so close to the Sun, actually within the Sun’s magnetosphere, it crosses these lines of force and sets off the charge for explosion. One wonders if the Moon were closer to Earth, say within the Van Allen Belts, if our sky would light up from continuous nuclear explosions. Currently, it is too far away to have much more than a tidal effect on the Earth. More another time.]

While electric motors simply transform electric current into a different voltage or amperage to produce work, the source of the electricity at the power plant comes from the turning of turbines. A mechanical or chemical source is required to turn these turbines: either from something which produces steam (coal, gas, or nuclear) or the movement of water (hydroelectric, tidal) or air (wind). A physical force is required to generate the electricity. These turning turbines make alternating current possible. The frequency of spin creates the frequency of charge.

Electricity can be produced also from chemical reactions (e.g. car batteries) and radioactive decay which represent a direct current. A region of static electricity – as in a capacitor or nebular cloud -represents direct current when it is discharged.

[Side Note #2: The Sun’s electrical output represents a direct current, although it could be argued that Mercury creates temporary alternating current effects as it orbits the solar magnetosphere.]

Understanding ley lines will be important to your survival after the next polar reversal event.


Local Magnetic Moraines

Behind my property there is a mountain called “Iron Mountain.” A century ago, iron was mined there; it was never mined out. The residual iron ore messes with my field compass. It pulls the needle slightly west. (Although the hardware underneath my dining room table has a far greater influence because of its closer proximity).

Local magnetic moraines exist in many sizes and shapes. While they do not overcome the influence of the Earth’s main magnetic field from its core – and for the most part they follow the Earth’s polar direction – they can produce local influences which differ somewhat.

When lava spews from the Earth, it contains no magnetic charge. It is too hot. When a substance reaches a certain temperature that it looses its polarity, it is called the Currie temperature.

As the lava cools, whatever direction the local magnetic field is pointing, the molecules will begin to point in that direction, as well. That is how scientists are able to determine whether a layer of rock comes from a period prior to a polar excursion or after. The local magnetic field will be locked-in and point in a direction different from the prevailing direction of the Earth’s core, especially if it is within strata that was formed during a catastrophic event.

When you use your field compass, your readings will only be relevant to where you are. If you decide to take readings in Chicago, Illinois today and then fly to Japan tomorrow, you cannot expect your readings to be the same. There might be differences merely a few miles away as you move from the influence of one ley line to that of another.

Measuring the direction and the strength of Earth’s magnetic field requires that you do it from the same location, also taking into account local factors.

Our tests are not measuring the change in direction of the compass. They are measuring the level of strength of the attraction.

Using the stopwatch method (SP31), we measured the time it took for the needle to return to a state of rest in the north polar position. You turned the compass at least 90 degrees and then quickly turned it back to the true north position, while at the same time, operating a stop watch. The longer it takes for the needle to return to a state of rest indicates that the Earth’s magnetic field is weakening.

The ruler method (SP32) measured the distance from the compass that was required for a magnet to move the needle by at least 30 degrees. A greater distance is another indication that Earth’s magnetic field is weakening.

Neither of these methods will be satisfactory for a scientist. You cannot get on the internet or a YouTube channel and declare that the field is changing at a global scale. However, over a period of months or years, a trend can emerge and a timeline calculated.


A Third Method for Calibration

A third method can be employed to confirm a trend: a pull test.

After you have recorded a reading from using the ruler method, you can use the magnet again. Only this time use the magnet to move the needle of the compass at least 45 degrees. With the aid of a stopwatch, quickly pull the magnet away and measure the time it takes for the needle to return to a state of rest in the north position. Record the time. Log the time alongside the distance recorded from your ruler test. Doing this should be a calibration. Both readings should indicate the same trend: whether the magnetic field of the Earth is strengthening, or weakening, or remaining the same. If there is a difference – one method indicating a change opposite from the other – then you need to repeat the test until you get consistent results. When you achieve consistent results, that can be your final reading to log for the day.

In coming months, I will return to the task of interpreting the data. But first, we need to learn more about what is really happening to Earth’s magnetic field and the different outcomes which are possible.
