Questions & Step-by-Step Solutions

In Biot-Savart Law, what does the term 'dL' represent?
  • Step 1: Understand that the Biot-Savart Law is used to calculate the magnetic field created by a current-carrying conductor.
  • Step 2: Recognize that the conductor can be of any shape, like a straight wire or a loop.
  • Step 3: The term 'dL' refers to a very small piece of the conductor's length.
  • Step 4: This small piece is called an 'infinitesimal element' because it is so tiny that we can consider it as a single point for calculations.
  • Step 5: When we sum up all these tiny pieces (dL) along the entire conductor, we can find the total magnetic field produced.
