How does the north pole of a magnet face th e north of the earth?
If the Earth's magnetic field were represented by a giant bar magnet through the poles, then the bar's magnetic south pole would be located at the Earth's north pole & vice-versa! We define magnetic north as where a compass needle's north pole points.
What atmospheric layer acts like a giant magnet and what does it attract?
The Earth's magnetic field is like a magnetic dipole, with one pole near the north pole and the other near the south pole.
What characteristics of earth makes it a giant magnet?
the molten iron core
If earth is a giant magnet why does the magnetic south pole correspond with the geographical north pole?
Good question ! The answer is that when scientists first began to investigate magnets, the pole of a magnet that tries to point North was called a "north-seeking pole". The word seeking was quietly dropped when people got tired of saying it. So, the magnetic pole in northern Canada is a south-seeking pole, or as we would say today, the South pole of a magnet. The earth's north-seeking pole is in Antarctica.An Alternative Answer'Magnetic North' and 'Magnetic South' are LOCATIONS, so-named to distinguish them from 'True North' and 'True South'. These terms have NOTHING whatsoever to do with the magnetic polarity of those locations.The ends of a magnet (or of a compass needle) are so-called because, when freely suspended, come to rest pointing in the directions of Magnetic North and Magnetic South. Originally, these were called the 'North-seeking' and 'South-seeking' poles of the magnet. Over time, we have dropped the word, 'seeking', and now simply call them their 'north' and 'south' poles. These are the magnetic POLARITIES of the magnet's ends. Since the 'north' pole of a magnet is attracted towards Magnetic North, the polarity of that location is south. So the earth behaves as though there is a giant magnet, buried within the earth, with its south pole locatedat Magnetic North and its north pole located at Magnetic South.
How does the earth behaves like a giant magnet?
Earth has a molten liquid core containing iron. It is believed that as it moves or spins, it creates an electric current that causes a magnetic field around the Earth. The field is believed to be created by this dynamo action. The magnetic field makes the Earth act like a huge magnet so it attracts like one. That's why it pulls the magnetized needle in a compass and makes it point in the general direction of the North Pole. Use the link below to learn more.
In what way is the earth a giant magnet?
In that it has a magnetic field - which can be detected by a compass needle.

Name of the physicist and their contribution?
One famous physicist is William Gilbert, an English physicist in the 1600s. He surmised that the Earth was a giant magnet with a magnetic field.
What layer acts like a giant magnet and what does it attract?
The Earth's magnetic field is like a magnetic dipole, with one pole near the north pole and the other near the south pole.

Who said the earth was a magnet?
The Earth is not a magnet. Its magnetic field is generated by electrical currents generated in the interior; or rather by the net sum of a number of separate electrical current processes. Nor is the strength or direction of the magnetic field fixed; it varies with time, and is well known to have reversed in polarity many times. The 'axis' of the Earth's magnetic field is not coincident with the spin axis - it is biased well off to one side.
Is the earth's core a giant magnet?
Earth's core is pretty much a dense, hot metallic sphere. It is hard because there has been so much pressure on it and heat. The outer core is indeed a magnet because scientists believe that it produces the earth's magnet field.
What characteristics of earth makes it a giant magnet?
the molten iron core
The first person to predict that the earth has a magnetic north and south pole is?
The idea that the Earth itself acts as a giant magnet was first proposed in 1600 by the English physician and natural philosopher William Gilbert. He was also the first to define the North Magnetic Pole as the point where the Earth's magnetic field points vertically downwards.
