... Interestingly the force on the dipole can be written in terms of the gradient of the potential energy, that is F(x) = −∇U (x) = ∇ [p · E(x)] which doesn’t quite look like the equation above. However, the two expressions are exactly equivalent. See Exercise 7 in Chapter 2 of your textbook for an expl ...

... Recall that the unit of magnetic field is Tesla (T ) and that of current is Ampere (A). 1. This constant µ0 is similar to the electric permittivity of the vaccum, 0 . But it is not the same thing. Also, just to make our life complicated, the constant µ0 appears in the numerator here while 0 is in ...
