Question

Which statements are true about the Biot-Savart Law? Biot-Savart is like Coulomb's Law, but for magnetic fields instead of electric fields Biot-Savart is the "brute force" method a computer would use to get the magnetic field H from a complicated arrangement of current sources. There is a simpler "magnetic potential" integral that's faster to calculate than the Biot-Savart integral. This is like electric potential, except magnetic potential is a vector. The magnetic field from a current source drops off as 1/distance^2
