I wondering if it is possible to create an electromagnet that has a diameter of 0.5 cm that can generate 75 - 100 lbs of pull force. I took physics in college so I have a basic understanding of how magnets work, but I don't have any practical knowledge. I don't know what is feasible.
I found an equation that describes what properties of a magnet need to be adjusted to accommodate for a desired strength and size:
F = (n x I)2 x mu x A/2g2
Thanks
I found an equation that describes what properties of a magnet need to be adjusted to accommodate for a desired strength and size:
F = (n x I)2 x mu x A/2g2
- F = force = 430 N
- I = current = 25 amps
- g = length of the gap between the solenoid and a piece of metal = 2 cm
- A = area = 7 mm2
- n = number of turns = 250
- mu = vacuum permeability = 4 x pi x 10-7
Thanks
