In summary, the formula for calculating the force between two electromagnets is complicated and depends on various factors. If the electromagnets are far apart, you can use the dipole approximation, but if they are close together, the Biot-Savart law is necessary. The specific parameters of the electromagnets, such as their size, number of turns, and current, will also affect the force. For more information and basic formulas, refer to Wikipedia.

mfb said:In general, those forces are complicated. If the electromagnets are far away from each other (relative to their size), you can approximate them as dipoles. Otherwise, the Biot-Savart law can be used.

See Wikipedia for basic formulas.

I have 2 iron cores with 10mm dia x 20mm length. with a coil with 500 turns of 0.3mm wire thickness, i guess i can pass 0.2 Ampere through that wire. The maximum distance between these 2 electromagnets is 15mm and minimum is 2mm

The force between two electromagnets is the attractive or repulsive force that exists between the two magnets due to their magnetic fields.

The force between two electromagnets can be calculated using the formula F = (μ0 * N1 * N2 * A) / (2 * π * r^2) where μ0 is the permeability of free space, N1 and N2 are the number of turns in each electromagnet, A is the cross-sectional area of the electromagnets, and r is the distance between the two magnets.

The force between two electromagnets is affected by the number of turns in each electromagnet, the cross-sectional area of the electromagnets, and the distance between the two magnets. Additionally, the strength of the magnetic field and the magnetic properties of the materials used in the electromagnets also play a role.

Yes, the force between two electromagnets can be increased by increasing the number of turns in each electromagnet, increasing the cross-sectional area of the electromagnets, or decreasing the distance between the two magnets.

The force between two electromagnets is used in various applications such as magnetic levitation trains, electric motors, and generators. It is also used in industrial processes for lifting and moving heavy objects, and in medical devices such as MRI machines.
