Question 1:

The Biot-Savart law is used to calculate:

Explanation: The Biot-Savart law is used to calculate the magnetic field produced by a current-carrying wire. It describes the relationship between the magnetic field, the current, and the distance from the wire.

Question 2:

The Biot-Savart law is a mathematical expression of:

Explanation: The Biot-Savart law is a mathematical expression of Ampere's law. It provides a quantitative relationship between the magnetic field and the current-carrying element producing the field.

Question 3:

Ampere's law relates the magnetic field along a closed loop to:

Explanation: Ampere's law relates the magnetic field along a closed loop to the current passing through the loop. It states that the line integral of the magnetic field around a closed path is proportional to the net current enclosed by the path.

Question 4:

Ampere's law is valid for situations with:

Explanation: Ampere's law is valid for situations with steady electric currents. It is not applicable for situations with time-varying or alternating currents.

Question 5:

The Biot-Savart law and Ampere's law both describe:

Explanation: Both the Biot-Savart law and Ampere's law describe the magnetic field produced by current-carrying elements. The Biot-Savart law focuses on calculating the magnetic field due to a small current element, while Ampere's law relates the magnetic field along a closed loop to the current enclosed by the loop.
