Absolutely not. First of all, "rare earth magnet ore", meaning the ores of metals like neodymium (Nd) and samarium (Sm), is not magnetic at all. It only becomes a magnet once you make a magnet out of it. For example, one such magnet is Nd2Fe14B and it only becomes a magnet after neodymium is combined with iron and boron. Naturally occuring neodymium ore ...

No. Cosmic radiation are high-energy particles that create particle showers high up in the terrestrial atmosphere. Those particle shower are heavily beamed downwards, and although in principle some secondary shower products feel the local magnetic fields, effectively are not affected by the natural terrestrial field, let alone weaker local fields. Those ...

Yes, there are maps that map out variations in the earth's magnetic field, example here http://science.gc.ca/eic/site/063.nsf/eng/97358.html. The large variations are primarily due to the presence of ferric materials, ie large deposits of material like magnetite. There are no areas of rare earth magnets as far as I know, given that rare earth magnets are ...

how can a complete novice find ore? You don't. In addition to Fred's excellent answer regarding the legalities of the matter, I would add the following: All of the easy stuff has already been found, and finding any more ore requires efforts beyond what you can do on your own. Stuff that is easy to find now is commonly in old mines or old mine tailings. ...

In other words where might be a natural place on Earth that would over power a compass and then some Just about anywhere where the rocks are rich in iron. This would occur near iron ore, basalt, gabbro, and similar iron-rich rocks. You really don't need a lot of magnetite in the rock for this to move the compass needle. You don't even need magnetite - ...

The rock you have is most likely not platinum ore. It appears to be sulfide ore most likely composed of galena, pyrite, and maybe copper sulfides such as bornite. It is more likely that your specimen is silver ore rather than platinum ore. Mexico has a long history of silver mining. There is a platinum deposit in southern mexico and it appears to ...

The magnetic field stops the charged particles mostly by trapping them along their fields lines (globally parallel to the ground at most latitudes, plunging to the ground near the poles (therefore allowing northern lights). If you 1up nature and build a massive electromagnet, you could at most create a secondary pole, which would act as particle channel to ...

Although the other answers have correctly pointed out that this isn't a relevant thing on Earth, it should be mentioned that such an effect does occur on the Moon: it is the likely cause for the Lunar swirls. These are though to be the result of magnetic anomalies causing local shielding of the surface from solar wind. This effect prevents the regions from ...

Magnetite is a type of iron ore and does not significantly affect the Earth's magnetic field. It would not protect you from cosmic radiation. However, cosmic radiation is more intense high in the atmosphere, so airline cabin crew and people living on high mountains are slightly more at risk. If you are worried about how to avoid radiation damage, the thing ...

This somewhat of a naive question. Firstly what type of ore do you want: iron ore, gold, tin, nickel, copper, silver-lead-zinc, lithium, ... etc. Also, the difference between an ore deposit and a mineral deposit is economics - can profit be made by digging it up, processing it and turning it into a saleable commodity: gold bars, ingot or sheets of copper, ...

Cluster in this situation refers to a grouping or a number of mining operations within a giving area. Sometimes deposits of minerals with sand deposits is such that a number of smaller deposits is created instead of one larger more continuous deposit. When this happens it sometimes makes more sense to mine the deposits as separate pits instead of one large ...
