Q: What is the unit of the physical quantity "Magnetic field intensity"?
  • A. joule per meter
  • B. newton per meter
  • C. kelvin per meter
  • D. Newton per ampere meter
Correct Answer: Option D - In any magnetic field if a charged conductor of unit length is kept transverse inside it and the electric current of unit ampere is passed through the conductor, then the force experienced by the conductor is called magnetic field intensity of magnetic field induction. It is a vector quantity and its SI unit is weber per meter square or Tesla.
