public class EddyCurrents

extends BaseObject

This BaseObject calculates the eddy currents due to a a magnetic monopole moving moving with velocity v

Field Summary

double	H H = height of the monople above z = 0
double	offset offset is an overall time offset before the image charges start moving
double	q0 zplane is the location in z of the conducting thin sheet
double	t the time
double	v v is the horizontal speed of the monopole
double	v0 v0 is the vertical speed of the receeding monopoles once they start receeding
double	xorigin xorigin is the x coordinate of the origin
double	yorigin yorigin is the y coordinate of the origin
double	zplane q0 is the magnetic charge

Constructor Summary

EddyCurrents(double H, double q0, double v0, double v, double offset, double xorigin, double yorigin)
constructor for the eddy currents

Method Summary

Vec3	Bfield(Vec3 X, Vec3 B) The eddy current of a moving monopole.
Vec3	Efield(Vec3 x, Vec3 E) This "E" field has no meaning for this object, as we are only using this object to calcuate the eddy current in the xy plane and put it in Bfield.
java.lang.String	toString() writes properties of the point charge to a string

constructor for the eddy currents

Parameters:

H - The height of the monopole above the plane.

q0 - The monopole charge.

v0 - The vertical speed of the receding monopoles.

v - The horizontal speed of the monopole.

offset - The time before the receding monopoles start receding.

xorigin - The x location of the monopole.

yorigin - The y location of the monopole.

Method Detail

Bfield

public Vec3 Bfield(Vec3 X,
                   Vec3 B)

The eddy current of a moving monopole. We put this in the "B field" so we can plot the eddy currents using our standard procedures in SundquistDLIC, but of course this is NOT a B field.

Specified by:

Bfield in class BaseObject

Parameters:

X - The position of the observer in the xy plane at z = 0.

B - The eddy current in the xy plane at z = 0 due to the moving monopole.

Returns:

B The eddy current in the xy plane at z = 0 due to the moving monopole.

Efield

public Vec3 Efield(Vec3 x,
                   Vec3 E)

This "E" field has no meaning for this object, as we are only using this object to calcuate the eddy current in the xy plane and put it in Bfield.

Specified by:

Efield in class BaseObject

Parameters:

x - the position of the observer

E - the electric field at the observer's position if the monopole is at p (calculated)

Returns:

zero for a stationary charge

toString

public java.lang.String toString()

writes properties of the point charge to a string
