What is the function of magnetic field?
Magnetic fields force moving electrically charged particles in a circular or helical path. This force—exerted on electric currents in wires in a magnetic field—underlies the operation of electric motors. (For more information about magnetic fields, see magnetism. The use of magnetic fields to generate electric current.
What is the first function of magnetic field?
The first function of the Earth’s magnetic field is to deflect most of the solar wind from stripping away directly the ozone layer that protects the Earth from the harmful ultraviolet radiation. Explanation: We are all familiar with the everyday magnetic objects.
How do planets have magnetic fields?
Magnetic fields around planets behave in the same way as a bar magnet. On Earth, flowing of liquid metal in the outer core of the planet generates electric currents. The rotation of Earth on its axis causes these electric currents to form a magnetic field which extends around the planet.
Why is Venus surface pressure so great?
Because Venus has such a dense atmosphere which is some 100 times thicker than the earth’s. This in turn caused the atmosphere to get warmer in a so-called runaway Greenhouse Effect. …
Does Mars have a magnetic north and south pole?
Since Mars is a rocky, terrestrial planet like Earth, one might assume that the same kind of magnetic paradigm functions there, too. However, Mars does not generate a magnetic field on its own, outside of relatively small patches of magnetized crust.
How do we get Mars magnetic field?
First we would have to somehow liquefy the outer core of the planet. Then the planet’s own rotation would create a dynamo and generate a magnetic field like Earth’s. This could be done using an extremely large nuclear bomb which would be placed near the core of the planet.
Can a magnetic field be created?
No, it is not possible to create magnetic waves without an electric field being present. Electric fields are created by electric charges. For instance, if you statically charged up a balloon by rubbing it on your hair, the balloon creates an electric field. Magnetic fields are created by magnets.
