Questions & Step-by-Step Solutions

What is the unit of magnetic field strength as derived from Biot-Savart Law?
  • Step 1: Understand that the Biot-Savart Law describes how electric currents create magnetic fields.
  • Step 2: The law involves a formula that includes current, distance, and a constant.
  • Step 3: The formula shows that the strength of the magnetic field depends on these factors.
  • Step 4: The unit of current is Ampere (A), and the unit of distance is meter (m).
  • Step 5: The constant in the formula has units that combine with Ampere and meter to give a new unit.
  • Step 6: When you work through the units in the formula, you find that the resulting unit for magnetic field strength is Tesla (T).
