Question

Which of the following statements correctly describes the Biot Savart's law and its applications
• The magnetic field \(dB\) from a current element is directly proportional to the current \(I\)
• The magnetic field is inversely proportional to the square of the distance
• It helps to determine the electric field around a stationary charge
• It is used to find the magnetic field at the center of a circular current loop Choose the correct answer from the options given below:

• A. A, B & D Only
• B. A, B, C & D Only
• C. A, B & C Only
• D. A & B Only

Hint:

Biot-Savart law: \[ dB\propto \frac{I\,dl\sin\theta}{r^2} \] It is used to calculate magnetic fields due to current carrying conductors.
