The potential energy U is equal to the work you must do to move an object from the U=0 reference point to the position r. The reference point at which you assign the value U=0 is arbitrary, so may be chosen for convenience, like choosing the origin of a coordinate system.


The energy is expressed as a scalar product, and implies that the energy is lowest when the magnetic moment is aligned with the magnetic field. The difference in energy between aligned and anti-aligned is where ΔU = 2μB The expression for magnetic potential energy can be developed from the expression for the magnetic torque on a current loop.

Potential energy is often wrongly defined as the energy at rest. The correct definition of Potential Energy is that it is the energy possessed by an object due to its position or configuration. Based on the word itself, objects that have potential energy must have the potential to do some work. A hanging flower vase […]

In order to calculate the potential energy of an object (PE), multiply the object's mass in kilograms (m) by the Earth's gravitational constant (g) and the height of the object from the floor in meters (h). and, by Equation 7.2.3, the difference in potential energy (U2 − U1) of the test charge Q between the two points is ΔU = − ∫r rref→F ⋅ d→l. Therefore, we can write a general expression for the potential energy of two point charges (in spherical coordinates): ΔU = − ∫r rrefkqQ r2 dr = − [ − kqQ r]r rref = kqQ[1 r − 1 rref].
