Q:

i want to know one thing ,suppose i placed a magnet with high value around (10^6 tesla) at some heigth above ground level ,then will this magnetic force of attraction produced by magnet have any affect on gravity pull ?

A:

That's an extremely strong magnetic field, far above anything we can obtain in the lab. There is some field energy associated with it, about 4*10

^{11 }J/cm^{3}. Via E=mc^{2}, we get a gravitational mass density of about 4*10^{-6}kg/cm^{3}or 4*10^{-3 }gm/cm^{3}. For comparison, water has 1 gm/cm^{3}and ordinary air has about 1.3*10^{-3}gm/cm^{3}. So it will show up a bit in gravity.Mike W.
