conductors
A great many things do not create magnetic fields. They includerock,plastics,most living things,most gases at normal conditionsActually most living things create magnetic fields measurable and commonly called brain waves. minute but measurable
They are called the magnetic field lines.
Magnetic lines of force are called magnetic field lines.
The magnetic force on Earth is called Earth's magnetic field or also the geomagnetic field.
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.
These magnetic disturbances are known as magnetic storms.
magnetic
Magnetic rock is called Lodestone.
The area of magnetic force is called a magnetic field. It is a region around a magnet or current-carrying wire where magnetic forces are experienced.
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.
Magnetic domains.
The area around a magnet where its magnetic force is felt is called the magnetic field.
