... In moving across an inductor of inductance L along (or against) the presumed direction of the current I, the potential change is ΔV = –L dI/dt (or +L dI/dt, respectively). Magnetic materials will change selfinductance by changing magnetic flux ...

Unit 14: Electric Charge
... o The fundamental quantity in electrostatics is electric charge. There are two kinds of charge, positive and negative. Charges of the same sign repel each other and opposite charges attract each other. o Conductors are materials that permit charge to move easily and insulators so not allow charge to ...
