Yea. Keep in mind that much of the energy used in the system was you hauling the weigt up the tree. The coeffeicent of gravity in the (newtonian) equation [math] F=G frac{m_{1} m_{2}}{d^2}[/math] is

[math]G =6.68 rm x 10^{-11}[/math]

and for electromagnet force in the equation [math] F=k frac{Q_{1} Q_{2}}{d^2}[/math] it is like

[math]k = 8.988 rm x 10^9[/math].

Gravity is a very weak force.

the power can be amplified
