Question

Which of the following properties cannot be calculated from Biot-Savart law?

• A. Electric field intensity
• B. Permeability
• C. Flux density
• D. Magnetic field intensity

Answer 1

Answer: (A)

Electric field intensity

Answer 2

The Biot-Savart Law calculates magnetic field intensity ($\vec{H}$) and magnetic flux density ($\vec{B}$) due to a current distribution. Permeability ($\mu$) is a constant used in the calculation, not an output derived from the current. Electric field intensity ($\vec{E}$) is unrelated to the Biot-Savart Law, which exclusively deals with magnetic fields produced by currents. Therefore, electric field intensity cannot be calculated from it.
