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.

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.

explanation:

firearm identification is the process of analyzing the bullets and cartridge cases left at a crime scene to determine if they came from a particular firearm. marks on the bullets and cartridges may be common to every firearm of that type. these are called class characteristics.

there are no contact forces mentioned on the list of choices that you've provided.
