Hang a magnetized object from a thread attached to its midpoint, so that it balances with its poles at the same level, like a propeller.
Notice that regardless of what position you point it, it has a direction in which it wants to point, and when you let it go, it always rotates itself to that direction.
An identical object that's NOT magnetized won't behave that way.
Plants don't have a significant magnetic field. Perhaps you mean "planets"?
The polar cusps, located above each pole, are funnel-shaped areas with near zero magnetic field magnitude in the Earth's magnetic field where solar wind particles have direct access to the Earth's ionosphere.
Lodestone is a naturally magnetized form of the mineral magnetite, which contains iron oxide. It possesses a permanent magnetic field due to the alignment of its iron atoms, which allows it to interact with Earth's magnetic field. When freely suspended, lodestone aligns itself with the Earth's magnetic poles, with one end pointing toward the magnetic north and the other toward the magnetic south. This property makes lodestone historically significant in navigation and compasses.
It fluctuates, including periodic reversals.
Just about any solid object will stop the solar wind. A sheet of aluminum foil would be effective. More important is the idea that magnetic fields, like planetary magnetic fields, deflect the solar wind. (This though a magnetic field is not a substance, per se.) Earth's magnetic field does a fine job of this.
You can't. The only thing the earth's magnetic field can tell you is the direction from where you are toward the earth's magnetic pole. That doesn't tell you anything about where you are.
The magnetic field periodically changes its orientation.
The earth as a single object has a magnetic field. If Uruguay is part of the earth, it shares the earth's magnetic field.
The orientation of a rock's magnetic field can tell you the direction in which the rock was formed, as the magnetic minerals in the rock align themselves with the Earth's magnetic field at the time of formation. It can provide insights into the geological history of the rock, including its age and past movements.
You can use a compass to detect the Earth's magnetic field and determine cardinal directions like North, South, East, and West. By aligning the compass needle with the magnetic field, you can navigate and orient yourself accordingly.
The Earth's magnetic field is the result of electrical currents flowing in the earth.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.
The vertical component of Earth's magnetic field is zero at the magnetic equator, where the magnetic field lines are horizontal. At the magnetic equator, the magnetic field lines run parallel to the Earth's surface, resulting in a zero vertical component.
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
No, the moon does not have a global magnetic field like Earth. Some localized magnetic fields have been detected on the moon's surface, but they are much weaker than Earth's magnetic field.
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Yes, the Earth has a magnetic field.
