I'm trying to understand the repulsive forces of solenoids. This is all paper as in I don't actually have them to test in real life. Take two solenoids that are equal to each other.
Specifications:
current is 10 amps
Number of turns is 300
Iron rod is 12 inches/ 304.8mm, with a Radius of 2 inches/50.8mm
Permeability of Iron (99.8% pure) µ (H/m) = 6.3×10−3
Relative permeability, μ/μ0 = 5000 (Source is wiki. I can give a link to the chart)
If I make it so that both the north polls are facing each other what will the repulsive forces be as I move them closer? For example- say the initial distance from one another is 5 inches/12.7 cm, then 2.5inches/6.35cm. I assume the force would increase as would a normal magnet.I'm unsure as to what formulas I need to apply, and depending on the complexity of said formula, how to reach an answer. Any help or advice would be very appreciated.
Thanks in advance,
Matt
