WebWe thus use the name electromotive force, abbreviated emf. Emf is not a force at all; it is a special type of potential difference. To be precise, the electromotive force (emf) is the potential difference of a source when no current is flowing. Units of emf are volts. Figure 1. WebSep 12, 2024 · Once the fields have been calculated using these four equations, the Lorentz force equation. →F = q→E + q→v × →B. gives the force that the fields exert on a particle with charge q moving with velocity →v. The Lorentz force equation combines the force of the electric field and of the magnetic field on the moving charge.
