    field - the field being evaluated
    
    position - The location to evaluate the force at
    
    velocity - The velocity to be considered during force evaluation. Useful for calculating drag.

  - linearGravityFieldWithVector
```
public static UIFieldBehavior linearGravityFieldWithVector(CGVector direction)
```
    Applies a force in the direction of the vector in the local space. To repel objects, use a negative strength. The force is the same everywhere in the field. Varies with the mass of the object according to F = ma
    
    Parameters:
    
    direction - The direction the force is applied in the x,y plane. The length of the direction vector is multiplied by the field's strength property to get the final calculated force. All components of the direction vector are used to calculate the length.
    
    See Also:
    
    direction
  - magneticField
```
public static UIFieldBehavior magneticField()
```
    The magnetic field is a uniform field in the positive-z direction (coming out of the screen). When the velocity of a charged dynamic item is perpendicular to the uniform magnetic field, the item feels a resulting force normal to both the velocity and the B field. This results CCW circular motion. You can adjust the strength of the B field to be negative which will result in circular motion being CW instead of CCW. An example use of this field is to make objects behavior differently from one another when they enter a region, or to make an object's behavior different than its mass based behavior. This field models the second part of the Lorentz equation, F = qvB

```
    A time varying differentiable Perlin simplex noise field. By default a smooth noise is calculated, and the field is time varying. To freeze the noise in place, set animationSpeed to 0.0. Mass is ignored.
    
    Parameters:
