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.

∙ 11y agoYou can show that the Earth has a magnetic field by looking at a magnetic compass.
The north end of the compass points to the north magnetic pole, and does so everywhere on Earth. It does this by aligning itself to the Earth's magnetic field. If there weren't a magnetic field, then a compass needle would not point to any consistent direction.

What does the presence of a magnetic field on Earth compared with other terrestrial plants indicate?
Plants don't have a significant magnetic field. Perhaps you mean "planets"?
What is polar cusp?
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.
How does Earth's magnetic field behave through long periods of geologic time?
It fluctuates, including periodic reversals.
What substance can solar winds not penetrate?
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.
What is induced by the rapid alternation of a magnetic field?
you would induce voltage therefore chanfing the magnetic field
How would you use the Earth's magnetic field to tell you where on Earth you are?
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.
How do i use the earth's magnetic field to tell me where to go?
..get a compass?
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.
What do lava samples tell scientists about what has happened to the earth magnetic field over geologic time?
The magnetic field periodically changes its orientation.
What is resion of Earth magnetic field?
The Earth's magnetic field is the result of electrical currents flowing in the earth.
What creates the Earths magnetic field?
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.
What is the magnetic force of this planet called?
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
Why does the earth have its own magnetic field?
The Earth's magnetic field is probably caused by convective currents in Earth's interior.
Earth's magnetic field is believed to be generated from what region?
If you mean the region of influence of the earth's magnetic field then its called the earth's magnetosphere
Does the earth have a magnetc field?
Yes, the Earth has a magnetic field.
Does the earths magnetic field cause the earth to tilt?
No. Earth's magnetic field does not affect its axis of rotation.
What is the leading theory for what causes earth's magnetic field?
The Dynamo Theory it what causes Earth's Magnetic Field
