– The force is perpendicular to both the velocity v of the charge q and the magnetic field B.

– I hope you remember what a Magnetic Force Field is as this requires a little of advanced physics ;-)

Linear motion: the particle velocity is aligned parallel to the magnetic field (θ=0).

Circular motion: the particle velocity is orthogonal to the magnetic field (θ=π/2).

Helicoidal motion: the particle velocity is neither orthogonal or parallel to the magnetic field.

– If you want to read something about particles moving in a Magnetic (and Electric) Field you can read this :Magnetic Force Field on Wikipedia.

– You can see the Linear, Circular and Helicoidal motions in this example where the arrows represent the magnetic uniform field:

– The bigger the strength the greater the effect on the particles and does no matter the distance from the magnetic (constant) field:

– You can try different distributions of the particles to find interesting simulations as in this example:

– I find next effect amazing! :
