How is the modulus of the magnetic induction vector determined?

The magnitude of the magnetic induction vector is determined by the ratio of the maximum force acting in a magnetic field on a segment of a conductor with a current to the product of the current strength by the length of this segment.

Remember: The process of learning a person lasts a lifetime. The value of the same knowledge for different people may be different, it is determined by their individual characteristics and needs. Therefore, knowledge is always needed at any age and position.
