No, a magnetic field is induced by moving electric charges. If a ferrous material (one containing iron) is placed in a magnetic field, the individual magnetic dipoles can be aligned in accordance with the magnetic field. Since the molten iron in the earth's core carries charges, a magnetic field is induced around the earth (with field lines coming OUT of the south pole and into the north). This magnetic field can align magnetic dipoles just as any man-made electromagnet can.
Industrial ceramic magnets otherwise known as large rotating drum magnets, are used by the metal scrap and recycling industries. The magnets are used to separate and process metals. If you are looking to recycle one of these magnets you can find a company that uses them for recycling.
There are 216 magnetic spheres that make up the Neocube, BuckyBall, Or Zen Magnets.
By definition a reservoir is manmade. Otherwise it's a lake or pond.
no

we are all natural because we weren't made in a factory we were made natural.Things that are made in factorys are manmade we are not manmade we are natural. Katrina LaChance- Bermuda138
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.
Magnets are not alive so they do not have cells at all.
since magnets are all ready magnetised when found in nature called natural magnet artificial magnets that are made by man are called artificial magnets
all magnets have two poles
magnets are used in class,at home or even in the loo!Everybody uses magnets all the time.You might be using one now,for all we know.
Manmade actually.
Manmade
No, magnets are not metal. Magnets are objects that produce a magnetic field, which can attract or repel certain types of metals, but they are typically made from materials like iron, nickel, or cobalt.
manmade
No. Magnets do not attract gold, silver, aluminum, brass, copper or lead. Magnets will attract nickel and iron or steel.
Well, yes, kind of. But they are not magnets, it's gravity.
