Tesla is a unit of _ per unit area.
Correct answer: A. Magnetic field lines
- A. Magnetic field lines
- B. Electric field lines
- C. Optical field lines
- D. Gravitational field lines
Explanation
The tesla (T) is the unit of magnetic flux density also called magnetic B-field strength. One tesla is equal to one weber per square meter. Using the equation , where E or magnetic flux density is equal to magnetic flux/ Area, (magnetic flux means magnetic field lines). Magnetic flux density (E) has units tesla and magnetic field lines have unit weber.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
