Introduction to Magnetism and Induced Currents

Introduction to Magnetism and Induced Currents

Magnetic fields permeate space and are strongest near a permanent magnet or electromagnet. IThe SI unit for B is the tesla (1 T = 1 Vs/m 2). The tesla is a fairly large unit of magnetic field, so we often list magnetic field strengths in terms of Gauss (1 G = 10 4 T). The magnetic field of the earth is about one half gauss in strength.

Inductance of a Coil Rotating in a Magnetic Field

Inductance of a Coil Rotating in a Magnetic Field

Inductance of the coil. As the coil rotates in the magnetic field, the induction flux through the coil changes and a timevarying current is induced in the coil. If an electric current passes through a coil, it generates a magnetic field around the coil. The magnetic flux of this field
