alleryStart learning →The net field of a current-carrying wire at a point is found from the Biot-Savart law using:
Asuperposition of fields
Bonly the nearest element
Cthe mean current value
Dconservation of energy only
Answer & Solution
Correct answer: A. superposition of fields
The law relies on the superposition principle: the fields of all current elements are added by integration.
