Question

The principle that predicts the magnitude of the force due to currents in a magnetic field is:

Answer 1

The Biot-Savart law

Step-by-step explanation:

Answer 2

The Biot-Savart law

Step-by-step explanation:

• The Biot-Savart Law describes the magnetic field created by a current-carrying wire, and allows the calculation of its strength at various points.
• To calculate the magnetic field resulting from a current distribution involves the vector product, and is normally a calculus problem when the distance from the current to the field point is continuously changing.
• The relationship between the magnetic field contribution and its source current element is called the Biot-Savart law.
