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).

Does the Earth have more than two magnetic poles?
The planet Earth has only two magnetic poles, north and south. They do not always stay in the same location, however.
How do you make a Magnetic forces?
by bring two magnets near we can make magnetic field for some distance.
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.
When the magnetic fields of two or more magnets overlap what is the results?
They will combine to make a single magnetic field.
What are the two main ingredients to make damper?
bread and water
What difference does distance make on the magnetic force of attraction between two magnets?
Magnetic force of attraction is invesely proportional to distance between two poles.
What two ingredients are needed to make succotash?
lima beans and corn
What are two kinds of fields that make up electromagnetic waves?
Electric and Magnetic
What are two conditions on earth that make the planet favorable for life?
