What is the magnetic effect of electric current according to Biot-Savart's Law?
Understand the Problem
The question involves concepts related to the magnetic effect of electric current, particularly focusing on Biot-Savart's Law and how to determine the magnetic field produced by a current-carrying wire at a given point.
Answer
Biot-Savart law relates magnetic field to current, length, angle, and distance.
The Biot-Savart law states that the magnetic field (dB) produced by a current element is proportional to the current (I), the length of the element (idl), and the sine of the angle (θ) between the current direction and the line joining the element to the point, and inversely proportional to the square of the distance (r) from the element to the point.

More Information
Biot-Savart's law is fundamental in understanding magnetostatics, explaining how electric currents generate magnetic fields, and is essential for calculations involving magnetic forces and fields in various applications.
Tips
Common mistakes include miscalculating the angle or distance, and not considering the vector nature of the magnetic field.
