    19.1 Introduction In this chapter, we will introduce Ampere’s law, which relates the magnetic field around a closed loop to the total electric current passing through the loop. Ampere’s law is an essential tool for calculating the magnetic fields generated by steady currents in wires and other conductive materials. 19.2 Ampere’s Law Ampere’s law states…

    Introduction A magnetic field is a vector field that describes the magnetic influence of electric charges in relative motion and magnetized materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength), so it is a vector field. Magnetic Force on a Moving Charge The force exerted…
