Answer:
B ( magnetic field ) , I ( current ) and Length Ā are dependent variables in the design
Explanation:
To design the required experiment
Given that our aim is to determine the relationship between the force on conductor and length of the conductor
First step : place a current carry conductor in an external magnetic field where the length of the conductor will be denoted as L
The magnitude of Force on the conductor will be :
F = B*I*XL = B*I*Lsinā
lets assume ā
= 90Ā° Ā then Ā F ā L Ā ( Force is directly proportional to the length of the conductor )
hence : Dependent variables here are : B ( magnetic field ) , I ( current ) and Length
