Solenoid Coil Electromagnetic Force Calculator
Calculate the force between a solenoid coil and another piece of ferromagnetic material using this calculator. Enter the values of current, area, number of turns and length of coil to find the result.
The magnetic field of solenoid is usually uniform along the axis and weak outside the coil
Solenoid Coil Electromagnetic Force Calculation
Code to add this calci to your website
F = (n x i)2 x magnetic constant x a / (2 x g2)
F = Force,
i = Current,
g = Length of the gap between the solenoid and a piece of metal,
a = Area
n = Number of turns,
Magnetic constant = 4 x PI x 10-7.
