How to analysis the size of the magnet magnetic case
Why magnet with magnetic , is the Earth 's rotation and its magnetic field because of the strong current will continue to combine , and finally the entire planet becomes a big field . Mineral earth such as nickel, cobalt, iron and other substances because of rotation of the Earth rotates to become a natural magnet.
We all know that there exists a gravitational field between substances. Similarly with the magnetic field pole is covered with a surrounding space . And the size of the imaginary number of the magnetic field can be used to indicate the magnetic lines of force , whose lines of force is more dense areas where the stronger the magnetic field , on the contrary , if the magnetic field lines of local thinning of the weaker .
In the motion of charged particles in a magnetic field would be called the Lorentz force . A charged particle in a magnetic field due to the different in the strength of the magnetic force of the magnet Lorenzi distinguished by the level of magnetic field strength . The Tesla is devoted to the amount of international units of magnetic flux density . The magnetic flux density is to describe the basic physical strong magnets magnetic field and magnetic field strength of the magnetic fields that describe the auxiliary .
