How the compass works?
The Earth has a magnetic field approximately like a magnetic dipole, with the magnetic field S pole near the Earth's geographic north pole and the other magnetic field N pole near the Earth's geographic south pole. A compass can determining direction relative to the Earth's magnetic poles by using a magnetized pointer (usually marked on the North end) which is pivoting free to align itself with Earth's magnetic field.
Earth magnet what?
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with the magnetic field South pole near the Earth's geographic north pole (see Magnetic North Pole) and the other magnetic field N pole near the Earth's geographic south pole (see Magnetic South Pole). This makes the compass usable for navigation. The cause of the field can be explained by dynamo theory. A magnetic field extends infinitely, though it weakens with distance from its source. The Earth's magnetic field, also called the geomagnetic field, which effectively extends several tens of thousands of kilometres into space, forms the Earth's magnetosphere. A paleomagnetic study of Australian red dacite and pillow basalt has estimated the magnetic field to be at least 3.5 billion years old.
What causes the part of earths magnetic field called the magnetosphere to exist?
Earth's magnetic field (and the surface magnetic field) is approximately a magnetic dipole, with one pole near the north pole and the other near the geographic south pole. The Inner Van Allen Belt & Outer Van Allen Belt cause the magnetic field.
What creates a magnetic field?
Both magnetic materials and moving electric charges induce magnetic fields. "A magnetic field can be created with moving charges, such as a current-carrying wire. A magnetic field can also be created by the spin magnetic dipole moment, and by the orbital magnetic dipole moment of an electron within an atom." A magnetic field can be produced by either a permanent magnet, or an electromagnet, the latter requiring suitable energization to function.
How do you make a sentence for magnetic field?
The magnetic field of the Earth protects us from cosmic radiation.
If a magnetic dipole is placed in a magnetic field the dipole is found to have both rotational and translational motion.what would you infer about the magnetic field?
Dipole not aligned with B field = rotational motion B field not constant along field direction = translational motion

Does Mercury have a magnetic field?
Yes. It has a modest magnetic field that is approximately aligned with the planet's axis of rotation. The field is a planetary dipole, and it is though to be generated in a manner similar to the way the earth is though to generate its magnetic field - dynamo action at or around the core. The strength of the field has been estimated as approximately 1% of Earth's. (see link)

What layer acts like a giant magnet and what does it attract?
The Earth's magnetic field is like a magnetic dipole, with one pole near the north pole and the other near the south pole.
What has occurred when rocks formed millions of years ago show the location of the magnetic poles at the time of their formation?
Magnetism is a property of certain materials, usually metals, that have an electric dipole on the molecular scale. A dipole is a significant separation between the positive and negative charges in the molecule. Since electrons and protons have spin, and moving electrical charges generate megnetic fields, the dipole generates a net magnetic field. If enough dipoles are oriented in the same direction the body has a net magnetic field. The dipoles can align when sitting in a permanent magnetic field for a long period of time, like underground in the earth's magnetic field.
Does Uruguay have a magnetic field?
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
