Chapter 4: Electric Potential
... F = mg = constant and F = qE = constant . Because the forces are analogous, we can conclude that the electrical force is also a conservative force and gives rise to a potential energy. This is called the electrical potential energy associated with a charge in an electric field. As we mentioned in th ...

... As a result of his own researchers, Gilbert himself proposed the real cause of the lining-up of a suspended magnetic needle or lodestone: The Earth itself is a lodestone and thus can act on other magnetic materials. Gilbert performed a clever experiment to show that his hypothesis was a likely one. ...

Electromagnetism Laws and Equations
... we generally cannot take the electric field E outside the integral, like we did with Gauss’s Law, as the electric field won’t be constant between the two points, i.e. the magnitude of E is a function of l.
