Field Detail

q

public double q

The magnetic charge of the monopole.

m

public double m

The mass of the monopole.

radius

public double radius

The Pauli radius of the monopole (repulsion always dominates inside this radius). Radius is the "Pauli" radius, that is the radius at which a r**(-12) repulsion sets in regardless of whether we have repulsion or attraction.

p

public Vec3 p

The position of the monopole.

v

public Vec3 v

The velocity of the charge.

zplane

public double zplane

The location of the the thin conducting sheet in z.

image

public int image

The image charge parameter for the monopole. If image = 0 this is just a normal monople. If image = 1 then this is a monopole whose magnetic and electric fields are non-zero only for observers with z > 0; if image = -1 then this is a monopole whose magnetic and electric fields are non-zero only for observers with z < 0
