Fields, models, and limits
Place positive and negative sources on a plane and sample the resulting vector field. Compare individual contributions with their vector sum and inspect where cancellation occurs.
Source charge and Separation experiment
Place positive and negative sources on a plane and sample the resulting vector field. Compare individual contributions with their vector sum and inspect where cancellation occurs.
What changed
Charge strength 5 and separation 35 change every local vector. The arrows sample a continuous field; they are not physical threads.
