Magnetic Field Due to Electric Current is an important topic in physics, particularly in the study of electromagnetism. This chapter covers the concept of magnetic fields created by a current-carrying conductor and the magnetic field strength of a long straight conductor, circular loop, and solenoid. It also deals with the right-hand thumb rule, Ampere’s law, Biot-Savart law, and their applications in calculating the magnetic field strength of different types of conductors.
This chapter is crucial for understanding the behavior of electric currents and their interaction with magnetic fields, which is essential for various applications in everyday life, such as in motors, generators, transformers, and various other electrical devices. It also has significant applications in the field of medical imaging, such as magnetic resonance imaging (MRI), and particle accelerators used in scientific research.
