What is the SI unit of magnetic field strength (magnetic flux density B)?
Answer and explanation
Correct answer: A. Tesla (T)
- Step 1: Magnetic flux density B is measured in teslas, where 1 Tesla = 1 Newton / (Ampere * meter) = 1 Weber / m^2.
- Step 2: Weber measures magnetic flux, Henry measures inductance, and Farad measures capacitance.
Answer
Tesla (T).
Why not the others: 'Weber (Wb)' is the unit of magnetic flux Phi; 'Henry (H)' is the unit of electrical inductance; 'Farad (F)' is the unit of electrical capacitance.
