# Force on Magnet from Electromagnet

• aarothepharo
In summary, the force on a magnet from an electromagnet is the result of the interaction between the magnetic field of the electromagnet and the magnetic field of the magnet, known as the magnetic force. This force can be calculated using the equation F = BIL, where B is the magnetic field strength, I is the electric current, and L is the length of the conductor, known as the Lorentz force law. Several factors affect this force, including the strength of the electromagnet's magnetic field, the distance between the magnet and the electromagnet, and the orientation of the magnet and the electromagnet. The force can be changed by adjusting these factors, and it is used in various technologies such as electric motors, generators, and speakers

Hello Everyone:
Take a look at the following diagram

Assuming the coil build above. How would you determine the force pushing-pulling the Neodymium Magnet in the center of the plastic pipe. I know the number of turns, length, amperage are in effect.

Forces between magnets are problems that are easy to write down but hard to solve. Depending on the setup, there might be some approximation that makes it easier. The general case: work out the energy in the fields for different positions (probably needs a numeric simulation), the gradient gives the force.
