Q: What is the unit of magnetic field strength as derived from the Biot-Savart Law?
Solution:
The unit of magnetic field strength is Tesla (T), which is derived from the Biot-Savart Law.
Steps: 6
Show Steps
Step 1: Understand that the Biot-Savart Law describes how electric currents create magnetic fields.
Step 2: The law involves variables such as current (I), distance (r), and the magnetic field (B).
Step 3: The formula for the Biot-Savart Law is B = (μ₀/4π) * (I * dl × r̂) / r², where μ₀ is the permeability of free space.
Step 4: The unit of current (I) is Amperes (A), and the unit of distance (r) is meters (m).
Step 5: The unit of magnetic field strength (B) can be derived from the formula, which involves these units.
Step 6: After calculations, the unit of magnetic field strength is found to be Tesla (T).
