Scientists have determined that the Earth's magnetic field is actually composed of an ecosystem of the microscopic organisms called Gorbuscha. They tend to stick together and contain little bits of magnetic matter, causing what scientists used to call the magnetic field. However, we know better now (thankfully!). These organisms compel the Sun's solar rays and protect us all from burning up. It also traps in heat so we on Earth don't die from the lack of heat. They, the so called "magnetic field" feast on tiny particles in space, mainly puny bits of debris from meteors, planets, stars, etc. Also, scientists have discovered that these little guardians of Earth are quite unpleased from us, humans wearing down the Earth and causing animals that the Gorbuscha have been with for so long to become extinct. Some scientists reason that if we don't stop our destruction of Mother Earth, these protectors'll let us shrivel and become extinct ourselves. This is what I've heard during a sleepover with friends, hope this helps! :)
A man named Richard Dixon Oldham discovered that the earth has a core. He determined this by studying the propagation of seismic waves from earthquakes. He hypothesized that the seismic waves had an origin, which he believed came from the center of the earth from a molten core.
They will combine to make a single magnetic field.
The space around a magnet where its magnetic effect can be felt is known as the magnetic field. It is a region where magnetic forces act on other magnetic materials or moving charges. The strength of the magnetic field decreases with distance from the magnet.
When a magnet is brought close to a piece of iron, the magnetic field of the magnet causes the atoms within the iron to temporarily align in the same direction as the magnetic field. This alignment creates a magnetic field within the iron, which then interacts with the magnetic field of the magnet, causing attraction between the two. The iron itself does not become permanently magnetized, it just responds to the external magnetic field of the magnet.
i don't know. I need to know i have this hw for Tuesday 28th April 2009 i don't know. I need to know i have this hw for Tuesday 28th April 2009
When the north pole becomes the south pole.
Scientists study the Earth's magnetic field by analyzing magnetic minerals in rocks. When these minerals solidify, they preserve the direction of the Earth's magnetic field at that time. By studying these rocks, scientists can see patterns of magnetic reversals happening over millions of years.
Scientists don't know the answer to that yet.
For one, the magnetic field changes continuously; this is not consistent with a permanent magnet.
i dont know its aload of bumf go away :p
Reversals of the Earth's magnetic field were first discovered through studies of magnetized minerals in rocks that record the orientation of the ancient magnetic field. By examining these rocks, scientists found patterns of magnetic stripes on the ocean floor that indicated periods of magnetic field reversals over Earth's history. These findings were further supported by evidence from deep-sea sediment cores and volcanic rocks.
Magnetic freild
Scientists can identify when a magnetic reversal happened by studying the magnetic orientation of rocks. This is possible because magnetic minerals in rocks align themselves with the Earth's magnetic field at the time the rock forms. By analyzing the orientation of these minerals in ancient rocks, scientists can determine when a magnetic reversal occurred.
Magnetic field
Scientists have found evidence of Earth's magnetic field reversals by studying the alignment of magnetic minerals in rocks. These minerals record the direction and strength of the magnetic field at the time the rocks formed, providing a historical record of past field reversals. Additionally, paleomagnetic studies of seafloor spreading have shown alternating patterns of magnetic polarity along mid-ocean ridges, supporting the theory of magnetic field reversals.
Yes. The Earth's magnetic field has reversed, so that the magnetic north pole has become the magnetic south pole, several times that scientists are sure of. We know this because when magma (molten volcanic rock) cools, it freezes the magnetic orientation that the Earth's magnetic field imposed on the liquid magma.
The stronger the magnetic field is.
