In Moving Charges and Magnetism, what is SI Unit of magnetic field?

There are two types of electricity - static and current. The current electricity is divided into Alternating Current (AC) and Direct Current (DC). Based on the production methods, electricity is divided into - heat, chemical, pressure, light and magnetism.

There are four types of power supply - switch-mode power supplies, linear power supplies, linear power supplies, and programmable power supplies

According to this law, at any point, magnetic field due to a tiny current element is directly proportional to the current element length.

The different types of magnetism are - Diamagnetism, Paramagnetism, and Ferromagnetism.

The exact formula for the magnetic force per unit length between two parallel current-carrying conductors:
