Electromagnetic Force Equation The aforementioned Lorentz force (electromagnetic) is calculated by: {eq}\vec F = q \vec E + q \vec v X \vec B {/eq} Where F is the magnetic force, E is the electric field, v is the velocity of the charged particles, and B is the magnetic field. ...
We are given the charge, its velocity, and the magnetic field strength and direction. We can thus use the equation F = qvB sin θ to find the force. Solution The magnetic force is F = qvB sin θ We see that sin θ = 1, since the angle between the velocity and ...
The electromagnetic structure of the stationary axisymmetric force-free magnetosphere around a black hole is characterized by the stream function ψ, the current potential I, and the angular velocity of the magnetic field lines ΨF. These functions are governed by the Grad-Shafranov equation. Possible...

In 3.5 there was a similar effect: variable names changes from small letters to capital letters. If you change from ec.Jx to ec.JX, it will work. Another problem is, that according to support this coupling of EC and MF includes not the complete equation; there is eps0*epsr*Att missing...
III. Magnetic Force on Moving Charges: According to the Laws of Electromagnetism, moving charged particles experience a force when subjected to a magnetic field. Known as the Lorentz force, it can be calculated using the equation F = q(v×B), where F represents the magnetic force, q is ...
