Solenoid Force

It is the load a solenoid can hold, pull or push at the starting point of its stroke.


F = (N*I)2 μ0 A / (2 g2)



  • μ0 = 4π×10-7
  • F is the force in Newtons
  • N is the number of turns
  • I is the current in Amps
  • A is the area in length units squared
  • g is the length of the gap between the solenoid and a piece of metal
