Gravity From Extreme Magnetism

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 ?

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*10¹¹ J/cm³. Via E=mc², we get a gravitational mass density of about 4*10^-6kg/cm³ or 4*10^-3 gm/cm³. For comparison, water has 1 gm/cm³ and ordinary air has about 1.3*10^-3 gm/cm³. So it will show up a bit in gravity.
