The principle of superposition applies to both fields. This is because the magnetic field is linearly related to its source, namely, the current element and the electrostatic field is related linearly to its source, the electric charge.
Which of the following is not a point of similarity between Biot-Savar...
The Biot-Savart law and Coulomb's law are both fundamental laws in electromagnetism and share several similarities. However, one point of dissimilarity between the two is the presence of magnetic monopoles.
Coulomb's law describes the electrostatic force between two point charges, where the force is directly proportional to the product of the charges and inversely proportional to the square of the distance between them. It assumes the existence of electric charges, which can be positive or negative, but does not allow for the existence of isolated magnetic charges or magnetic monopoles.
On the other hand, the Biot-Savart law describes the magnetic field generated by a current-carrying wire. It states that the magnetic field at a given point is directly proportional to the current, the length of the current element, the sine of the angle between the current element and the line connecting the element to the point, and inversely proportional to the square of the distance between the element and the point. The Biot-Savart law allows for the existence of magnetic charges or magnetic monopoles, which have not been observed in nature.
Therefore, the absence of magnetic monopoles is a point of dissimilarity between the Biot-Savart law and Coulomb's law.
