The core of the planet must be a ferromagnetic material (like nickel-iron), and the core must be molten so that the mobile fluid will generate the field through dynamo action. It is this dynamo action that is thought to generate the earth's magnetic, and is believed to be the source of the magnetic fields of other planets. It is important to note that this is a widely accepted idea, but is not proven. The tools necessary to prove it do not currently exist.

What are 2 uncommon materials that are magnetic?
Two so called rare earth materials that are magnetic are neodymium and samarium.
What are two science skills and how scientists might use them to learn more about this distant planet?
observing pictures of the terrain; inferring what the images are; measuring the distance between features (such as rocks); interpreting meteorological information to try to understand the climate on Saturn
Why does a compost attract to a north magnetic and repel by the south?
OK- first, it is a compass. The needle of a compass is a magnet. It points to the Eath's Magnetic Poles- the two spots where the Earth's magnetic field comes out of the ground. In magnetism, opposites attract, likes repel.
What does pole mean in magnet?
Sailboats have many "poles". The ones that I think you are referring to are the mast and the boom. The Mast is the Tall one that sticks up out of the hull. The is connected horizontally to the mast.
What are the two components of a wave of light?
Electromagnetic waves do not require a medium to travel (light, radio).
How do you make a Magnetic forces?
by bring two magnets near we can make magnetic field for some distance.
Does the Earth have more than two magnetic poles?
The Earth has two main magnetic poles, the North Pole and the South Pole, where the magnetic field lines converge. However, there are also localized areas where the magnetic field is strong, leading to additional poles known as magnetic anomalies.
Is there a magnet field on the planet mercury?
Mercury does, despite its small size, have a magnetic field, and the planet is approximately a magnetic dipole (meaning the field has only two magnetic poles). Data from the space probe Mariner 10 led to its discovery in 1974, at which time the probe measured the strength of the magnetic field to be about 1.1% of that of earth, but it's strong enough to divert solar radiation and therefore creates a magnetosphere around the planet.
What are the two main ingredients to make damper?
bread and water

lima beans and corn
What are two kinds of fields that make up electromagnetic waves?
Electric and Magnetic
What are 2 elements that make up the center of the earth?
The two main elements that make up the center of the Earth are iron and nickel. These elements are thought to be present in a liquid state due to the immense heat and pressure at the Earth's core, contributing to the planet's magnetic field.
What are two conditions on earth that make the planet favorable for life?
he and she
What two ingredients are used to make soap?

Why do you need two North Poles?
== == Earth happens to have two North poles, but it is not necessary. * The geographic north pole is one of the two places where the axis of rotation meets the surface. All planets and stars have one geographic north pole and one geographic south pole. * The north magnetic pole is the point where the magnetic field points directly down, and the south magnetic pole is the point where the magnetic field points directly up. Earth happens to have one magnetic north pole and one magnetic south pole at the moment. Mars doesn't have any magnetic poles. Our sun often has dozens of magnetic north and magnetic south poles in or near its sunspots.
What are two ingredients that make things rise?
Both baking powder and yeast can make things rise.
What are two effects of Earth's magnetic?
Earth's magnetic field can make magnets out of ferromagnetic material and it affects the movements of electrically charged particles in space.
