Ah, let me share with you the beautiful world of magnetic fields! Just like a gentle breeze flowing from north to south, magnetic field lines also travel from the north pole of a magnet to its south pole. It's all part of nature's way of creating balance and harmony in the world around us. Let's appreciate the simple wonders of physics today!
The arrow that points north in the compass is attracted to the magnetic north pole, using magnetic waves generated by the earth. Even though the magnetic north pole is several miles from the rotational north pole, it helps you go north.answ2. Only the second statement above is true. The earth's magnetic field is generated by electrical currents flowing roughly parallel to the Equator. These are generated, we believe, by the hot magma.Your compass needle does NOT point north. Rather, it aligns itself with the magnetic lines of force at your location. But the local magnetic north may well be quite different from the real north. This is called the magnetic deviation in your region.
what instrument was invented by Chinese to show direction
Lodestone, a naturally magnetized mineral, is attracted to the Earth's magnetic field and aligns itself with the north-south direction. This property allows the lodestone to point toward the Earth's magnetic north pole when suspended freely.
That all depends on WHERE on the earth you are located. The angle between the direction to the north geographic pole and the north magnetic pole is different at different places. Go to "Google.com" and search for "magnetic declination". You'll get plenty to read, and ways to determine what the angle is at your location.
First of all, we're pretty sure that you're referring to "variation", not "declaration".Magnetic variation is the difference between the direction from you to the north pole (called "true north"), and the direction in which your magnetic compass points.That difference changes with your position on earth, because the north pole and theplace your compass points to are two different places. If you were standing at the point that's exactly halfway between them, then your compass would point exactly away from the north pole. And if you're not between them, but you're standing on the extension of the line between them, then your compass it pointing at the north pole, because both points are in the same direction from you.If you look at a navigational map, you will see lines of magnetic variation printed on the map. If you read your magnetic compass and apply the magnetic variation (printed on the map), you can calculate the direction of TRUE north.
The direction of magnetic field lines are from north to south
Yes, magnetic field lines go from north to south.
The arrow on magnetic field lines shows the direction in which a north magnetic pole would be drawn if placed in the field at that point. This convention is used to represent the magnetic field direction moving from north to south.
Magnetic field lines point from the south pole to the north pole of a magnet.
The lines around a bar magnet represent the magnetic field lines, which indicate the direction in which a magnetic north pole would be pushed when placed in the field. These lines are typically drawn from the north pole to the south pole of the magnet, showing the magnetic field's direction and strength.
Magnetic field lines show the direction in which a magnetic north pole would be attracted. They provide a visual representation of the strength and direction of the magnetic field in a given space.
Curved lines are used to represent magnetic field lines. The closer together they are, the stronger the magnetic field. Arrows are added to show the direction a north pole would move if placed at that point.
The direction of the magnetic field is from north to south.
The lines around a bar magnet represent the magnetic field. They indicate the direction in which a magnetic north pole would move if placed in the field. The density of the lines indicates the strength of the magnetic field.
Magnetic field lines. These lines represent the direction in which a small north magnetic pole would tend to move if placed at any given point in the field.
The magnetic field lines go from the north pole to the south pole outside the magnet and from the south pole to the north pole inside the magnet.
The direction of magnetic field lines inside a magnet is from the south pole to the north pole. This means that the field lines are directed from the region of higher field intensity (south pole) to the region of lower field intensity (north pole) within the magnet.
