I formulated a statement about the repulsion between a permanent magnet and an air core coil (electromagnets without a ferromagnetic or ferrimagnetic core), and I believe this statement is true, but I would like to seek the opinion of others about it:
"In a system where an electromagnet made from an air core coil (electromagnet without a ferromagnetic or ferrimagnetic core) is in repulsion against a permanent magnet, the stronger is the magnetic field of the permanent magnet the stronger will be the force of repulsion between the electromagnet and the permanent magnet, with the volts and amperes of the direct current (DC) in the electromagnet being kept the same"
Is my statement correct?
Please try to answer this without any prejudices in mind. No preconceived ideas about "what I'm trying to do here".
Replacing the permanent magnet by another permanent magnet with a stronger magnetic field will make the force of repulsion between the permanent magnet and the air core electromagnet stronger, even if the electromagnet keeps getting the same volts and amperes of direct current?
By the way, consider the coil is made from copper wire, that is a diamagnetic material.
