Magnetic Materials

Magnetic Materials. www.phy.iitb.ac.in/~ph102. Magnetic Material. Magnetic field in materials is due to tiny electric current loops or magnetic dipoles . At normal temperatures the magnetic moments of the dipoles are randomly oriented so that the net magnetic moment is zero.

Voltage Induced in a Loop Rotating in a Constant Magnetic Field

Voltage Induced in a Loop Rotating in a Constant Magnetic Field. Important points to consider: The area vector is perpendicular to the plane of the loop. Sketch the problem. ? must be in rad/s. V max occurs when sin ? t = 1. V min occurs when sin ? t = 0. Use radian mode.
