Thank you very much I think I have a fairly reliable approximation now. I was able to get a formula that seems simple enough. lucky for me I'm not planing on going into electrical engineering.

It does seem rather complicated. http://www.goudsmit-magnetics.nl/EN/Background-information/About-magnetic-lifting I believe that the lift capacity of my set-up would be about 90-95% of the lifting force.

the cross-sectional area is 1.2668x10-4 m I have also been wondering how direct the relationship between the magnetic force and lifting capacity is, If a electromagnetic force of 16 N is able to lift approximately 1.63 kg of steel then it becomes possible to estimate the relative permeability...

That is true, I have an "i" magnet. What equation would I use then?

I don't think the effects would be so extreme if that were the only reason. I am thinking it could be caused by the mass I'm lifting and its addition to the length of the system. If this is the cause than there is far to much complexity in the field path for my ability level and understanding of...

Hello, I have been performing an experiment in which I am observing the lifting capacity of DC electromagnets while changing variables including current, number of turns, and length of the core. It is a fairly basic experiment as all the theoretical values can be obtained using the formula...

how would the gravitational constant help? F=ma GMEm=mv2 r2 r the only thing i can think of would be v2=GME r but then i have two unknowns the v and r.

Homework Statement what would be the total mechanical energy of a 200 kg satellite in a geosynchronous orbit around the earth? The only known data is the radius of the Earth and mass of the Earth the mass of the satellite, m=200 kg, it would have a period of T=24h, but i do not know the radius...
