Pairs - although monopoles have long been speculated about!
OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
The Earth's magnetic field protects the biosphere from harmful radiation from the sun: particularly charged particles. These the magnetic field forces to turn and travel along the magnetic lines of force where they do at last penetrate the Earth's atmosphere at the magnetic poles. This is the source of the Northern Lights. These locations are therefore locales of high harmful radiation. The fact that they are are currently in high north (and south) means that there isn't too much life there to get harmed by it. If the north magnetic pole were to be in the Amazon Rain Forest we would see a large area where life was adversely affected by the radiation.
Lots of things can change it like a bigger planet right next to earth, a black hole, even humans. Those are the things I can come up with so far, but all I know that it has to be either huge and/or destructive. If the liquid center of the Earth is charged and rotating, it creates a magnetic field. If the rotating is reversed, for any reason, the magnetic field reverses.
Actually no. Magnetic north shifts over time. It has to do with the rotation of the liquid iron inside the earth. I can't remember the exact number but I think you can estimate true north by adding 5 degrees to your compass.
The north pole of a compass needle points to a location we call 'Magnetic North'to distinguish it from 'True North'. Since 'unlike poles attract', the magneticpolarity of Magnetic North is obviously south.But when we talk about the Earth's 'north pole' or 'south pole', we're almostalways talking about the poles of its rotation, at 90° north and south latitude.Those points have no connection to the north and south magnetic poles, andcompasses don't point to them.
Let me tell u something the answer is pairs.
The third law of magnetism states that magnetic poles always come in pairs - a north pole and a south pole. This law is similar to the concept of electric charge in that opposite poles attract each other, while like poles repel.
The law of attraction of magnetic poles states that opposite magnetic poles attract each other, while like magnetic poles repel each other. This law governs the interactions between magnetic materials and explains how magnets behave.
Geographic poles refer to the Earth's axis points where it meets the surface (North and South Poles), while magnetic poles refer to points where the Earth's magnetic field is the strongest. These poles do not align exactly; the geographic poles are fixed, while the magnetic poles can shift position over time due to changes in the Earth's magnetic field.
The Earth's magnetic poles do not align perfectly with the geographic North and South poles due to the planet's molten iron core generating a magnetic field that is not perfectly symmetrical. This causes the magnetic poles to shift and be slightly off from the true geographic poles.
Gauss's law for magnetism states that magnetic monopoles do not exist. This means that magnetic poles always come in pairs, with a north pole and a south pole together.
Let me tell u something the answer is pairs.
The Earth has two main magnetic poles, the North Pole and the South Pole, where the magnetic field lines converge. However, there are also localized areas where the magnetic field is strong, leading to additional poles known as magnetic anomalies.
This is known as magnetic reversal when earth's magnetic poles change places.
True. The magnetic poles move constantly.
No, Earth's magnetic poles and its geographic poles are not in the same place. The geographic poles are the points where Earth's axis of rotation intersects its surface, while the magnetic poles are where the planet's magnetic field lines converge and enter/exit the Earth. The magnetic poles are constantly moving and can deviate from the geographic poles.
Like magnetic poles repel. For instance, the North Pole will always repel another North Pole. Such poles have the same charges and cannot transfer them to each other, a condition that would lead to attraction.
