Question

how to calculate the magnetic force of an electromagnetic solenoid?​

Answer 1

F = (Fm)2 μ0 A / (2 g2)

F = (N*I)2 μ0 A / (2 g2),

Where:

μ0 = 4π10-7

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.

Answer 2

Answer:

Calculate the force by writing the equation :

F = (n×i) ^2 × magnetic constant × a/(2×g^2)
