The magnetic field is defined as the concentration of magnetism created in the middle of a magnetic charge in a given space. The magnet is the creator of the magnetic field and the establishment of this charge in a specific space. In the same way that the electric charge and the mass create the electric and gravitational field, respectively, the magnet will be responsible for the creation of the magnetic field.

In a vector image it is possible to observe the magnet, represented in figure by a given vector B. Induction lines, thus, will pass from the vectors with magnetic characteristic, and will be directed from the north pole to the south.

Tesla's T confers the representation of the international unit of measurement representative of the magnetic field.

Define, with your words, the purpose of the magnetic induction lines in a magnetic field, relating them to the magnetic forces.
