Please answer question completely!

Initially, two identical springs are attached vertically to a ceiling. These springs support a copper rod in equilibrium as shown below. The rod is then connected to a battery using wires of negligible mass. The battery rests on a table (not shown). Also, an external magnetic field "B" is "turned on"; "B" is uniform in the vicinity of the rod and is directed out of the paper (toward you). The source of "B" is not shown. After just a few moments, the rod is once again in equilibrium, having risen a height Deltax. If the mass of the rod is 0.03 kg, find the tension in each spring, both in its initial configuration (Ti) and in its final configuration (Tf).

Explanation / Answer

T (initial)= 0.03g/2 = 0.15 N

T(final) = 0.15-BIL/2

L=length of rod

I= current = E/R
