public ZeroProbe()

Method Details

fieldMagnitude

public float fieldMagnitude(float x,
 float y,
 float z)

Description copied from class: FieldProbe

Get the field magnitude in kiloGauss at a given location expressed in Cartesian coordinates.

Specified by:

fieldMagnitude in interface IField

Overrides:

fieldMagnitude in class FieldProbe

Parameters:

x - the x coordinate in cm

y - the y coordinate in cm

z - the z coordinate in cm

Returns:

the magnitude of the field in kiloGauss.

getMaxFieldMagnitude

public float getMaxFieldMagnitude()

Description copied from class: FieldProbe

Obtain the maximum field magnitude of any point in the map.

Specified by:

getMaxFieldMagnitude in interface IField

Overrides:

getMaxFieldMagnitude in class FieldProbe

Returns:

the maximum field magnitude in the units of the map.

isZeroField

public boolean isZeroField()

Description copied from class: FieldProbe

Checks whether the field has been set to always return zero.

Specified by:

isZeroField in interface IField

Overrides:

isZeroField in class FieldProbe

Returns:

true if the field is set to return zero.

gradient

public void gradient(float x,
 float y,
 float z,
 float[] result)

Description copied from class: FieldProbe
