A solenoid displaces a material plunger ferromagnetic at a distance of 1 cm. The inductance of the solenoid in function of the position of the plunger is given by: L(x) = 0,05 – 20000((x- ro)) H, where x ranges from 0 to 0.01 m and xo = 0.25 m Is there a point where the force generated in the plunger is zero? If so, for what value of x?

Question
A solenoid displaces a material plunger ferromagnetic at a distance of 1 cm. The
inductance of the solenoid in function of the position of the plunger is given by:
L(x) = 0,05 – 20000((r - xo)) H,
where x ranges from 0 to 0.01 m and xo = 0.25 m
Is there a point where the force generated in the plunger is zero? If so, for what value
of x?
