How is earths magnetic field used by people and animals?
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.
Minerals in igneous rocks can show the direction of earths?
The Earth magnetic field changes approximately every 200,000 thousand years.
How do earths magnetic field magnetize an iron bar over many years?
Ferromagnetic materials are randomly distributed, but in a magnetic field, they can become aligned in the direction of the magnetic field. The earth's magnetic field has a fairly stable direction over very long time periods (many thousands of years). :D hope u injoy
How many magnetic poles are there on the earths surface?
2
What is it called when rocks are different because Earths magnetic poles change places?
Magnetic Reversal. Several magnetic reversals have occurred over geologic time.
Switch in direction of earths magnetic north and south poles?
Magnetic Reversal
Why do scientists think that earths' magnetic field has not always pointed north?
Every 100,000 years or so, the Earths magnetic field shifts direction. North becomes south, south becomes north.
How is earths magnetic field used by people and animals?
People use Earth's magnetic field for navigation, such as in compasses to find direction. Animals, like birds and fish, can sense Earth's magnetic field to navigate during migration or find their way in the ocean.
How a magnetic compass can be used to find directions on Earths surface?
A compass is an instrument containing a freely suspended magnetic element which displays the direction of the horizontal component of the Earth's magnetic field at the point of observation.
What forms when earths magnetic field changes direction?
When Earth's magnetic field changes direction, it results in a phenomenon known as geomagnetic reversal or magnetic flip. This process involves the magnetic north and south poles switching positions. These reversals have occurred throughout Earth's history and have been recorded in the rock record.
Is a compass affected by the earths magnetic field?
Yes, a compass works by aligning itself with the Earth's magnetic field to determine direction. The needle in a compass is magnetized and will point towards the Earth's magnetic north pole.
Earths magnetic field can make a magnet out of an iron bar by causing the magnetic domains to?
align in the same direction, creating a magnetic field within the iron bar. This alignment occurs due to the interaction between the Earth's magnetic field and the magnetic properties of the iron, resulting in the iron bar becoming magnetized.
Minerals in igneous rocks can show the direction of earths?
The Earth magnetic field changes approximately every 200,000 thousand years.
The possible source of earths magnetic core is?
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
Is earths core a source of earths magnetic field?
Yes.
Earth's magnetic field results from the spinning of the?
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.
Does the earths magnetic field has periodically reversed direction?
Yes, the Earth's magnetic field has periodically reversed its direction throughout history. These reversals are known as geomagnetic reversals and have occurred many times over the past few million years.
