SUMMARY
To calculate the attractive force of an electromagnet, one must consider the current flowing through the coil, the number of turns in the coil, and the magnetic permeability of the core material, typically steel. The formula for calculating the magnetic force is F = (μ₀ * N² * I² * A) / (2 * g²), where F is the force in Newtons, μ₀ is the permeability of free space, N is the number of turns, I is the current in amperes, A is the cross-sectional area of the coil, and g is the gap between the magnet and the object being lifted. For a target force of 10 Newtons, precise calculations based on these parameters are essential.
