Electromagnet repulsion increased significantly

AI Thread Summary
When two electromagnets are aligned with the same current direction and placed with like poles facing each other, they repel each other due to magnetic forces. The repulsive force increases linearly with the magnitude of the currents in the magnets, as described by the formula relating to the product of the currents. The geometry of the coils and their configuration can enhance the magnetic force, suggesting that engineering improvements can lead to stronger interactions. The shape of the core, such as using a pentagon or octagon, may contribute to increased structural rigidity and potentially enhance the magnetic strength. Understanding these principles can help in designing more effective electromagnet systems.

when two electro magnets are coiled the same and same direction of current are placed S to S so they repell... is the force acting upon them to separate ( push away ) exponentially increased (when they are very close) as each of the separate magnets current is increased?
is there a formula I am looking for?
 
Physics news on Phys.org
The magnetic force between two current carrying wires is proportional to the product of the currents i1 * i2. The constant of proportionality depends on the geometry of the coils and can be increased by engineering, but the dependence of the force on the magnitude of the currents is always a simple linear relationship.
 
that makes sense, i figured it worked like that :smile: what's that you say about geom and the force can be increased with proper engineering? are you referring to the shape of the core which the coils are wrapped around? can a metric pentagon or octagon bar increase the strength of the force because of the structural rigidity?

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...
