Nothing - The polarity of an electromagnet depends on the direction of current flow and you can effect the same change in orientation to the earth's field by moving the electromagnet rather than the earth's field.
Any magnet will always align itself to north south direction of earths magnetic field. Magnetic needle will always be perpendicular to the direction of current. Stronger magnets attracts weak magnets towards itself if the weak magnet is placed in stronger magnets magnetic field.
Earth's magnetic field created by earths magnets deflects cosmic rays which damage our biosphere.
It is done with a device that harnesses the earths magnetic field and separates the individual north pole and individual south pole magnets. You can read about it at GOD BASED MAGNETISM.
Most magnetic alloys are based on one or more of the following:ironnickelcobaltHigh field strength modern alloys also contain rare earth metals.
Compass magnets align themselves with Earth's magnetic field due to their own magnetic properties. Electromagnets, like the one found in devices such as phones or microwaves, can create magnetic fields that may interfere with a compass's accuracy if they are strong enough and placed close to the compass.
Earth's magnetic field can make magnets out of ferromagnetic material and it affects the movements of electrically charged particles in space.
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Objects such as compass needles, charged particles like electrons and protons, and solar wind are all influenced by Earth's magnetic field along its magnetic lines. These particles can be deflected or trapped by the field as they move through space.
Yes.
The earths magnetic field results from deep in the earths core. Magnetic conduction from within the earths core is believed to be the cause of this.
Yes, magnets are essentially metal ores that can be found many places in Earths surface.
Earth has a magnetic field that is generated by the movement of molten iron in its outer core. This magnetic field helps protect our planet from harmful solar radiation and guides compass needles to point north. The strength of Earth's magnetic field has been decreasing over time and periodically reverses its polarity.
