- A.Current
- B.Magnetic flux density
- C.Force
- D.Length of the wire
Model answer
What a good answer should say
- Force
Explanation
Why this works
In the required practical, the primary variable being measured is the force acting on the wire when it carries a current in a magnetic field. This force is influenced by the current, magnetic flux density, and length of the wire.
