PPT-Magnetic moment of a current loop:

current area enclosed by current loop Orbiting electrons form a current loop which give rise to a magnetic field For the electron the Bohr magneton is the simplest model possible to the smallest possible current to the smallest possible . Consider a uniform magnetic field into the board, with conducting rod moving through it:.  . + side. - side. Charges will move. If part of a circuit, can generate a current!. Which direction is the current through the resistor?. . Circulating Charges . (Charge +q in a uniform magnetic field). Since the particle is tracing out a circle of radius of r, we could calculate the time it takes to the particle to undergo one full revolution.. Chapter. 30. Copyright © 2014 John Wiley & Sons, Inc.
