Ampere's circuital law

Ampere's circuital law states that the magnetic field generated around a closed loop is directly related to the amount of electric current passing through the loop. Essentially, if more current flows through a wire, the magnetic field created around it becomes stronger. The law provides a way to calculate this magnetic field by examining the current enclosed within a chosen loop, making it fundamental for understanding how electromagnets, transformers, and electric motors work. In simple terms, electric currents produce magnetic fields, and the law quantifies this relationship.
