1 tesla is equal to:
Correct answer: B. I NA-1m-1
- A. I NAm-1
- B. I NA-1m-1
- C. I NA-1m
- D. I N-lAm
Explanation
It is independent to area of cross section (radius) of solenoid. The Tesla unit has, for example, a corresponding validity in the SI system too: here it is indicated by the units of measure kilogram and meter. For the time measurement, the second is also used. The SI units Tesla and Gauss are therefore not basic units of measurement: the magnetic flux density can finally be calculated from the force of moving charges. The following relationship applies: A Tesla is equal to a Newton per meter and ampere. An exemplary example illustrates this: It corresponds exactly to the flux density of a Tesla, which exerts on a 1 meter long electrical conductor, which in turn conducts a current of 1 ampere, exactly 1 Newton attraction. The necessary magnetic field is created by the current flow in the conductor or by the moving electrons.

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.
