Many of today's electronic devices require magnets to function. This reliance on magnets is relatively recent, primarily because most modern devices require magnets that are stronger than the ones found in nature. Lodestone, a form of magnetite, is the strongest naturally occurring magnet. It can...
A ceramic magnet known as lodestone, or magnetite, was the first magnetic material discovered and occurs naturally. Even though the ceramic magnet has been around for so long, they weren't commercially produced until 1952. Although they're common and keep their magnetism, they tend to have a ...
But to prove this, we would have to find some kind of magnetic sensory organ in birds. And we are not sure that we have. 但为了证明这点,我们得在鸟的器官里找到某种磁场感应器官。我们不确定我们是否找到了。 We have found in birds a mineral called magnetite, which we think might be somehow...
But there’s new buzz in the industry now after the Lucara Diamond Corpannouncedthe recovery of an exceptional 2,492 carat diamond from its Karowe Diamond Mine inBotswana, and declared that this remarkable find is one of the largest rough diamonds ever unearthed. According to the announcement, ...
Below you will find descriptions of seven different tests you can do to determine if the rock in question is ameteorite. Observe the Exterior Fusion crust When a meteorite is falling through the atmosphere, it begins to heat up because of the extreme compression of the atmosphere. The meteor ...
Large deposits of magnetite dotted Scandinavia. With a strong desire to find new land to explore (and pillage), the Vikings fashioned their own compasses around 1000 CE. Thecompass in question consisted of a magnetized iron needlein a piece of straw that they placed in a bowl of water. The...

Some animal species do have the ability to detect the magnetic field, however, and they use it to make their migrations. Bats and sea turtles use magnetic information to find their way [source: PhysOrg]. Some species of bacteria even rely on the magnetic field to orient themselves [source:...
What is the chemical formula for magnetite? What is the relationship among rocks, minerals and chemical elements? Is halite a halide mineral? What are the types of native element minerals? What property can be used to distinguish talc from gypsum? What do all carbonate minerals have in common...
