Hi. Here is the data for electromagnet
Wire material = copper
Turns = 160
AWG = 22
Iron Core = Steel bolt, ¾-13 thread, 2” long.
Resistance = 0.65 Ohms.
I = v/r = 9/ 0.65 = 13.84A
So If I connect typical 9V 200mA battery, how can I calculate how much weigth it can pull and for how long.

The pull of an electromagnet depends on a number of things. No only the amp-turns but the material of the core, its saturation, the size of the core and whether the opposing end is brought around to form a horseshoe.
It also depends on the material and thickness of the "pole piece" and the contact distance between the poles and the pole piece. These things will make a difference of more than 10:1
