PURPOSE: To illustrate the geometry for line integrals.
DESCRIPTION: The small square along one horizontal axis represents the route around which the line integral may be determined. It can be translated and/or rotated for a variety of situations.
SUGGESTIONS: This model might be helpful in discussing Maxwell's equations in integral form.
REFERENCES: (PIRA unavailable.)
EQUIPMENT: Line integral model, as photographed.
SETUP TIME: 5 min.
