flux. The magnetic field lines through the area. The ratio between the magnetic flux per area perpendicular to the magnetic field, called density magnetic flux or the size of the magnetic field
, according to the relationship B = when a large magnetic flux (a unit is bordered by Weber) locations. A scene with a unit square meter area B is the magnetic flux density is measured in Weber per square meter, or tesla.
