Electromagnet with Adafruit motorshield

I ended up doing around 2000 turns on each which measured between 25.2 ohms for the lowest and 26.8 ohms for the highest. then I took off from the high ones so they were all 25.2-25.5ohms.

With an 11.1V battery I should get about 10.5V actually being used on the electromagnets(after the motor shield voltage drop) so I will have V=IR 10.5 volts = (.42 amps)(25 ohms) so .42 amps drawn for each

I think everything looks great here. If for some reason its too strong I can use a 7.4V battery and get 6.9 volts=(.276 Amps)(25 ohms)

Oh that makes sense on speed. Thanks!
