The crew  switches on the electromagnetic pulse to keep the Sentinels at bay.

            Thoughts are electrical impulses in the brain. It is known that powerful electromagnetic pulses can subdue the thinking process. Neuroscientists use Transcranial Magnetic Simulation (TMS) to help ease depression, enhance cognition, and even fight fatigue. Interestingly, spiritual techniques like yoga, meditation, and positive thinking also create similar fields. The crew of The Nebuchadnezzar using EMP to influence The Sentinels is the equivalent of using a spiritual technique to settle down the negative activity of the mind.

          Sentinels are negative thoughts in our mind which blind us from knowing the reality of the world. In Matrix movie sentinels are the symbolism of these negative thoughts which keeps once in a while attacking a spiritual aspirant who wants to set free from the prison of the mind (matrix). But these negative thoughts attack in zillions when the spiritual aspirant goes to the source of his “being”. This is what is shown in the revolutions, when Neo leaves to the source, zillions of sentinels attack Zion.
