Question

Одинаков ли модуль вектора магнитной индукции магнитного поля постоянного магнита вблизи этого магнита и вдали от него

Answer 1

Да когда дальше меньше

Answer 2

Similarity of Magnetic Field Induction Vector Module

The module of the magnetic field induction vector near and far from a permanent magnet is not the same.

The magnetic field induction, also known as magnetic flux density, is a vector quantity that represents the strength and direction of a magnetic field. Near a permanent magnet, the magnetic field induction vector module is stronger, while it decreases as the distance from the magnet increases. This phenomenon is described by the inverse square law, which states that the strength of the magnetic field decreases with the square of the distance from the source.

The magnetic field induction near a permanent magnet is influenced by the magnet's properties and the distance from it. As the distance increases, the magnetic field strength diminishes, resulting in a decrease in the module of the magnetic field induction vector.
