As we all know The Earth has a magnetic field. Why the objects on the surface of the Earth do not get magnetized? It is possible to measure the magnetic field frequency of the Earth?
They do. The magnetic field of Earth is not strong enough to make powerful magnets, but it is sufficient to leave a measurable trace in some types of rock.Akmalidin said:Why the objects on the surface of the Earth do not get magnetized?
It is a static field. It changes over long timescales, but not in a periodic way so "frequency" is not a very meaningful concept.Akmalidin said:It is possible to measure the magnetic field frequency of the Earth?

The magnetic field of the Earth is a natural phenomenon that surrounds and protects our planet. It is created by the movement of molten iron in the Earth's outer core.
The magnetic field of the Earth plays a crucial role in protecting us from harmful solar winds and cosmic radiation. It also helps animals, such as birds and sea turtles, navigate.
No, the magnetic field of the Earth is not constant. It is constantly changing in strength and direction, and even undergoes complete reversals every few hundred thousand years.
Scientists use a device called a magnetometer to measure the strength of the Earth's magnetic field. This can be done on the surface or from satellites in space.
There is evidence that human activities, such as mining and drilling, can have a small impact on the Earth's magnetic field. However, these changes are negligible compared to the natural variations of the field.
