Magnet Berikut Ini Yang Bekerja Dengan Memanfaatkan Medan Magnet Bumi Adalah. – If you have ever used a compass (either the traditional mechanical one or the one built into your Smartphone), you know it always points north. If you suspend a refrigerator magnet, it will also mean north. It suggests that the Earth under your feet generates a magnetic field all around us! As we know, a magnetic field acts like a protective shield around the Earth; this Earth’s magnetic field repels and traps charged particles from the Sun. In this article, let us know in detail about the [Magnet Berikut Ini Yang Bekerja Dengan Memanfaatkan Medan Magnet Bumi Adalah.]
Magnets that Work Utilizing the Earth’s Magnetic Field
A magnet utilizing the Earth’s magnetic field is a needle magnet. This magnet, a tool that functions as a direction indicator, is often used in compasses. The needle magnet in the compass is left free so it can rotate to point in the direction. The attractions in the North and south of the Earth will always attract the ends of the needle (poles). The following is a picture of a compass with a magnetic hand:
What Is Earth’s Magnetic Field
The geomagnetic field is the extra name for Earth’s magnetic field. The Earth’s magnetic field resembles a bar magnet and stretches millions of kilometers into space. Antarctica is home to the magnetic north pole, and the Earth’s south magnetic pole is close to the north pole! Because of this, the north pole of a compass magnet points north (since the North and south poles attract). Although it is pretty weak in field strength, the Earth’s magnetic field is vast. 40,000 nT, as opposed to the power of a refrigerator magnet, which is 10.
Although it is pretty weak in field strength, the Earth’s magnetic field is vast—a modest 40,000 nT as opposed to the 107 nT of a refrigerator magnet.

Theory of Earth’s Magnetism – Magnet Berikut Ini Yang Bekerja Dengan Memanfaatkan Medan Magnet Bumi Adalah
The origin of the Earth’s magnetism is explained by one idea:
Dynamo effect: Because metallic fluids are present in both the inner & outer cores of the Earth, each generates its lines of magnetic field. The solidified components are found in the inner core, while molten iron is in the outer body.
What Causes Earth’s Magnetism?
Convection currents of melted iron and nickel in the Earth’s core produce the planet’s magnetism. These currents have Magnetic fields, which also carry charged particle streams. The solar wind is comprised of ionizing charged particles deflected by this magnetic field so that it cannot penetrate our atmosphere. Without this magnetic shield, the solar wind might have gradually destroyed our atmosphere, ending all life as we know it. Because Mars lacks a magnetic field to shield it, it lacks a robust atmosphere suitable for supporting life.
The north and south poles on Earth are not the same as the planet’s magnetic poles. The magnetic north pole is in Antarctica, while the magnetic south pole is in Canada. The Earth’s rotational axis is inclined by roughly 10 degrees concerning the magnetic poles. Thus, your compass was pointed towards Canada the entire time rather than the actual North!
Components of Earth’s Magnetic Field
The Earth’s magnetic field is caused by three factors, which also determine its direction and strength:
- Declination of magnetism
- Magnetic dip angle or magnetic inclination
- component of the Earth’s magnetic field that is horizontal
