It is Earths' "Magnetosphere".
They are called the magnetic field lines.
A Magnetic Force
The speed of rotation of the magnetic field is called magnetic flux. It is a measure of the flow of a magnetic field through a particular area.
The space around a magnet where its magnetic influence can be felt is called the magnetic field. It is the region in which magnetic forces are experienced due to the presence of the magnet.
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
They are called the magnetic field lines.
The area around a magnet where its magnetic force is felt is called the magnetic field.
Magnetic lines of force are called magnetic field lines.
Have you ever seen a magnet? Did you see the field? There you go. While you can't see the field itself directly, you can see the effects of the field if you use iron filings or something like that; they'll line up with the magnetic field lines
the area of magnetic force around a magnet is called the magnetic field
All materials are magnetized when placed in the magnetic field . The material magnetized by the effect of a magnetic field is called magnetic permeability.
The configuration of all lines of force around a magnet is called a magnetic field. The magnetic field represents the way in which magnetic forces are distributed in the space surrounding a magnet.
