How do magnetic stripes form on the ocean floor? The magnetism is a property of certain elements with certain geometry of their electron spin, such as iron. There is iron in minerals of basalt , the rock that comes from lava erupting along Mid ocean ridges. As these minerals cool, the magnetic domains (like subcrystalline regions that act like a magnetic dipole line up with the prevailing external magnetic field and get frozen in that alignment, becoming a property of all the

Earth's magnetic field Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.

- Because the Earth is made of magnetic elements such as Iron, Nickel, and Cobalt, the Earth acts as an extremely large magnet, which attracts these charged particles, among other things.lasmasphere: a region inside the magnetosphere which captures plasma that flows from the ionosphere, so that there is a plasma build-up. Pole: an extremity of an axis through a sphere; in a magnet, one of two places where it is most intense; the two poles have opposite charges (+/-).

What is the earths magnetic fields function? However, unlike the field of a bar magnet, Earth's field changes over time because it is really generated by the motion of molten iron alloys in the Earth's outer core (the geodynamo). The Magnetic North Pole wanders, fortunately slowly enough that the compass is useful for navigation.

How Does a Compass Work? The Earth is a magnet that can interact with other magnets in this way, so the north end of a compass magnet is drawn to align with the Earth's magnetic field. Because the Earth's magnetic North Pole attracts the north ends of other magnets, it is technically the South Pole of our planet's magnetic field. True north.

Why does the Earth have a magnetic field? It does seem clear that the generation of the magnetic field is linked to the rotation of the earth, since Venus with a similar iron-core composition but a 243 Earth-day rotation period does not have a measurable magnetic field.eport Abuse. The short answer is that we are not entirely sure why Earth has a magnetic field. The other answer is that the outer core acts like a magnet. This implies that it is like magnets that people put on their refrigerators.

Earth's magnetic field The magnetosphere is created by the magnetic field. It is the area around the Earth that acts as a shield against the harmful particles in solar wind. The magnetosphere has many different layers and structures, and solar wind shapes each of these layers.he Earth’s magnetic field is created by the rotation of the Earth and Earth's core. It shields the Earth against harmful particles in space. The field is unstable and has changed often in the history of the Earth.

Earth's Core 1,000 Degrees Hotter Than Expected That's as hot as the surface of the sun. The difference in temperature matters, because this explains how the Earth generates its magnetic field. The Earth has a solid inner core surrounded by a liquid outer core, which, in turn, has the solid, but flowing, mantle above it. There needs to be a 2,700-degree F (1,500 C) difference between the inner core and the mantle to spur thermal movements that — along with Earth's spin — create the magnetic field.

- A natural shield has been found to protect the Earth from killer electrons. View gallery (3 images) The idea of putting a Star Trek-like force field around the entire Earth seems like the fodder for a fairly silly science fiction epic out of the 1930s, but according to space scientists, such a barrier already exists.

Science for Kids The magnetic field the outer core creates goes way out in to space and makes a protective barrier around the earth that shields us from the sun's damaging solar wind. Inner Core. The Earth's inner core is made up of iron and nickel, just like the outer core, however, the inner core is different. The inner core is so deep within the earth that it's under immense pressure. So much pressure that, even though it is so hot, it is solid.
