Earth's magnetic field Unlike a bar magnet, however, Earth's magnetic field changes over time because it is generated by a geodynamo (in Earth's case, the motion of molten iron alloys in its outer core).The North and South magnetic poles wander widely, but sufficiently slowly for ordinary compasses to remain useful for navigation.he Earth and most of the planets in the Solar System, as well as the Sun and other stars, all generate magnetic fields through the motion of highly conductive fluids. The Earth's field originates in its core. This is a region of iron alloys extending to about 3400 km (the radius of the Earth is 6370 km).

Triceps brachii muscle It is commonly believed that the radial nerve also provided motor innervation to the long head of the triceps. However, a study conducted in 2004 determined that, in 20 cadaveric specimens and 15 surgical dissections on participants, the long head was innervated by a branch of the axillary nerve in all cases.

Magnetic Field of the Earth The magnetic field magnitude measured at the surface of the Earth is about half a Gauss and dips toward the Earth in the northern hemisphere. The magnitude varies over the surface of the Earth in the range 0.3 to 0.6 Gauss. The Earth's magnetic field is attributed to a dynamo effect of circulating electric current, but it is not constant in direction. Rock specimens of different age in similar locations have different directions of permanent magnetization.

- The Earth is like a giant magnet because it generates a magnetic field and has a North and South Pole. The Magnetic North pole is attracted to the Geographical South Pole, a … s opposites attract.he magnetic polarity of 'Magnetic North'  is a south pole, and the magnetic polarity of 'Magnetic South' is a  north pole. This explains why the 'North-Seeking' pole of a compass  is attracted towards Magnetic North. Answered.

MAGNETIC DECLINATION The earth also has a magnetic field, though the magnetic south pole is at the place we usually call the North Pole. A compass needle is a magnet, and the north side is pulled towards the earth's South Pole.

- About Magnets. A magnet produces a measurable force called a magnetic field. Static magnets have magnetic fields that do not change (unlike electromagnets, which generate magnetic fields only when electrical current flows through them). Magnets are usually made from metals (such as iron) or alloys (mixtures of metals, or of a metal and a nonmetal).

Enchanted Learning Search THE EARTH'S MAGNETOSPHERE. The magnetosphere is the Earth's magnetic environment. The Earth is a huge dipole (2-pole) magnet. The Earth's magnetic field is probably cause by its molten iron-nickel core. This magnetic field is aligned with the north and south poles, and has reversed many times during geologic history.

magnet An object that attracts iron and some other materials. Magnets are said to generate a magnetic field around themselves. Every magnet has two poles, called the north and south poles. Magnetic poles exert forces on each other in such a way that like poles repel and unlike poles attract each other. A compass is a small magnet that is affected by the magnetic field of the Earth in such a way that it points to a magnetic pole of the Earth.

- Earth has magnetic field with North & South Poles. The axis of rotation is different from the magnetic poles. This difference creates force for the earth to rotate on its axis. The same is the case with all planets in the Solar System.

- Earth's electromagnetic field is created by a spinning molten iron outer core The movie states that the Earth's EM field is created as a result of the liquid outer core spinning in one direction at roughly equal and constant velocity all over. • Yes, magnetism is caused by moving charges.arth's molten iron outer core has stopped rotating. The cause for the movie's scenario of the Earth's EM field to start to collapse is that the Earth's outer core, which is a ball of molten iron the size of Mars spinning at 1,000 miles an hour, somehow stopped spinning, all of a sudden. • This is simply impossible.

Magnetic Field of the Earth The Earth's magnetic field is similar to that of a bar magnet tilted 11 degrees from the spin axis of the Earth. The problem with that picture is that the Curie temperature of iron is about 770 C.

John F. Kennedy exists and is an alternate of. Merge this question into. Split and merge into it. Answered by The Community. Making the world better, one answer at a time. In a very real sense, the Earth is an electromagnet. It has an iron core with magnetic fields that operate electrically as the mantle rotates above the core.

The Earth: Facts Another amazing attribute of the earth are the magnetic poles and their fields. The core of the earth produces a field of magnetic energy which surrounds the planet much the same way as the magnetic field of a common bar magnet. The magnetic north allows the needle on a compass to point towards that direction.

- Do other planets have magnetic fields like our Earth? It is great that our Earth possesses a magnetic field because it protects us from harmful particles in the solar wind. The Earth’s magnetic field curves outward near the South Pole, turns upward, and reenters the Earth near the North Pole.

How Does the Magnetosphere Protect the Earth? How does the magnetosphere protect the Earth? A: The Earth's magnetosphere protects the planet from solar winds and high-energy particles by redirecting this energy around the planet. When charged particles approach the Earth, the magnetosphere affects them due to their magnetic properties. Particles blown by the solar wind simply sweep around the Earth, while slower radioactive particles may become part of the Earth's radiation belts, held safely above the surface by the magnetosphere.

CONTENTS Our understanding of the origin to magnetic fields in planets is very poor. We know that the Earth's magnetic field is not due to the presence of a giant permanent magnet, such as iron, deep in the Earth's core because 1) the core temperature is above the Cure temperature and 2) the field is too variable.ur understanding of the origin to magnetic fields in planets is very poor.

magnetism One remarkable property of magnets is that whenever a magnet is broken, a north pole will appear at one of the broken faces and a south pole at the other, such that each piece has its own north and south poles.rom his study of magnetism, C. A. Coulomb in the 18th cent. found that the magnetic forces between two poles followed an inverse-square law of the same form as that describing the forces between electric charges.

Magnetic Fields 1 The reasons why Venus does not have a global magnetic field are that it spins very s-l-o-w-l-y (about once every 243 Earth days!) and the absence of convection in the liquid core (probably because of the lack of plate tectonics for the past half billion years). Mercury is a bit surprising because it has a weak magnetic field. 2  Mercury is the smallest of the terrestrial planets, so its interior should have cooled off long ago. 3  Also, Mercury spins slowly---once every 58.8 days. 4  Mercury's high density tells us that it has a proportionally large iron-nickel core.

- The rotation of the Earth and the resultant convection currents in the Earth's core are responsible for our magnetic field, which protects us from solar radiation and gamma rays. If the Earth reverses its rotational direction, there will be a period during which the magnetic field diminishes or totally collapses.

Magnetic Poles: Definition & Shifts And that's where the names come from. The 'North pole' of any magnet is the one that would be attracted to the Earth's North magnetic pole. In that sense, they are just labels that identify the opposite magnetic force produced at each end of the magnet. The Earth's magnetic field also has poles, North and South.
