What is the significance of field lines in a vector field?
They indicate the direction and strength of the field.
Fill in the blank: The density of field lines represents the _______ of the field.
strength
What is the mathematical representation of a field?

What is the role of contour lines in field drawing?
They represent levels of constant value in a scalar field.
Fill in the blank: In a vector field, the direction of the vector indicates the _______ of the force.
direction
What is meant by ‘field visualization’?
The graphical representation of field data to analyze and interpret the behavior of the field.
Multiple Choice: Which method is commonly used to visualize scalar fields?

What does the divergence of a vector field represent?
The rate at which ‘stuff’ is expanding or contracting at a point.
True or False: The curl of a vector field measures the rotation of the field.
True
