The total electromagnetic force on a charge can, then, be written as \begin{equation} \label{Eq:II:13:1} \FLPF=q(\FLPE+\FLPv\times\FLPB). \end{equation} This is called the Lorentz force.

There the magnetic force is the whole force. It didn’t look...

This case can be treated using the Lorentz force equation (5.1.1) for the force vector f acting on a charge q [Coulombs]: f = q( E + v ×μoH) [Newtons] (Lorentz force equation) (5.1.1) where E and H are the local electric and magnetic fields and v is the charge velocity vector [m s-1].
29 Νοε 2023 · The direction of the force is found from Fleming's left hand motor rule (which you may need to look up). It is at right angles both to the bar and to the magnetic field. It's up to you to apply this to your problem. Alternatively, you can apply the magnetic Lorentz force formula, $\vec F=q\ \vec v \times \vec B$ to the
If we have both electric and magnetic fields, the total force that acts on a charge is of course given by F~ = q E~ + ~v c ×B~!. This combined force law is known as the Lorentz force. 10.1.1 Units The magnetic force law we’ve given is of course in cgs units, in keeping with Purcell’s system.
The Lorentz force causes charged particles to exhibit distinct rotational (“cyclotron”) and translational (“drift”) motions. This is illustrated in Figures \(\PageIndex{1}\) and \(\PageIndex{2}\).
A wire fashioned into a pendulum moves inside a magnetic field, demonstrating the Lorentz force. A charged particle moving through an applied magnetic field experiences a force that is at right angles to both the direction in which the particle is moving and the direction of the applied field.
φ This formula can be taken as the absolute value of the following cross product: F → = I l → × B → where the vector l → represents the length and direction of the wire. The force acts therefore perpendicular to the direction of the wire and the magnetic field lines.
