ANikola Tesla
BHans Oersted
CAlbert Fert
DEdwin Hall
Answer & Solution
Correct answer: A. Nikola Tesla
1. Magnetic field strength B is defined through the force on a charged particle moving in the field.
2. Its SI unit is the tesla, written T.
3. The unit is named after the inventor Nikola Tesla.
4. The gauss is the other named unit here, and it is smaller than the tesla.
