Of True North and Magnetic North and Compass North which way is really up?

True North is the real North, following along the lines of longitude which converge at the North Pole, the farthest geographically North point on the planet, and the rotational axis of the planet. Magnetic North and Compass North are both the same thing, with the compass pointing along Magnetic North. Magnetic North however, is not the real North. If you were to follow your compass as far North as it could point, you would end up on the Prince of Wales Island in the Northwest Territories of Canada, over 1,500 miles away from the North Pole. Magnetic North can be adjusted to True North on your compass by knowing the local magnetic variation of your area and adding/subtracting accordingly. A third North is Grid North, which follows the Grid Lines on a standard map. At the South Pole, every direction is True North, so Grid North is used instead and can be found by following the Prime Meridian northwards. Hope that helps.

How is lodestone formed?

Lodestone is a piece of magnetite that is naturally permanently magnetic. Magnetite is a natually-occuring mineral found as several percent of granite or many volcanic rocks and about one-hundredth of sedimentary rocks such as sandstone. Magnetite, normally magnetic only when placed in an ambient magnetic field, that is, it is an induced magnet. However, magnetite occurs in outcrops among other minerals and rocks. If such occurences of magnetite are on a hilltop, prominently above nearby hills, lightning will strike that hilltop, millions of times over time. Lightning is electrical current, and as with any current, has an associated magnetic field, which permanently aligns the "magnetic domains", or put in English, magnetizes the mineral. In other words, the magnetite is then 'permanently magnetized' and can then attract other induced magnetic objects such a paper clips, iron objects, other pieces of magnetite and can even be made into a magnetic compass. Next time, you are at the seashore or near a stream, dip a small magnet in the water, swish it around among the sand or dirt and then see the magnetite particles sticking to it. sheldon@breiner.com
