Which of the following is a similarity between Biot-Savart's Law and Coulomb's Law?
Answer & explanation
Correct answer: option 3
- The electrostatic field is along the displacement vector joining the source and the field point. The magnetic field is perpendicular to the plane containing the displacement vector r and the current element I dl.
- Biot-Savart's Law deals with vector source. The electrostatic field is produced by a scalar source, namely, the electric charge.
- Biot-Savart's Law depends upon the angle of the observation point with the source element which is not the case in Coulomb's Law.
