22 lip 2022 · Learn what magnetic energy is, how it is calculated, and how it is used in various devices. Magnetic energy is a form of potential energy associated with electric charges in motion and magnetic fields.
For a derivation of this, see the derivation in Section 3.4 for the potential energy of an electric dipole in an electric field. Also, verify that the dimensions of the right hand side of Equation \ref{7.7.1} are \(\text{ML}^2 \text{T}^{−2}\) (energy).
Now, we are able to determine the change in potential energy for a charged particle moving along any path in space, given the magnetic field. At this point, it is convenient to introduce the electric potential difference \(V_{21}\) between the start point (1) and end point (2) of \({\mathcal C}\).
Magnetic potential energy is the potential energy stored in a magnetic field. It is the energy required to bring a magnetic object from an infinite distance to a specific point in the magnetic field, against the magnetic force.
9.1: Introduction to Magnetic Potential The force on a charge q in a magnetic field is qv×B . This force (the Lorentz force) does not depend only on the position of the particle, but also on its velocity (speed and direction).
