Salt strengthens water's ability to conduct electricity. When a electromagnet is placed near salt water, it creates a moving magnetic field in the water due to salt water's conductive properties. The salt water then creates an opposing magnetic field.

There is a pretty comprehensive breakdown of how it works around 12:30. Basically, by allowing the salt water to move between the magnets, there is a voltage induced across the magnets. This is because the salt water is concentrated with ions, which carry charge.

Half-fill two containers with seawater. Attach one end of the wire to the iron electrode; the other end is attached to one side of the light bulb base. Do the same with the other wire, except that you must connect it to the magnesium electrode. Submerge both electrodes into the container of seawater.
Salt strengthens water's ability to conduct electricity. When a electromagnet is placed near salt water, it creates a moving magnetic field in the water due to salt water's conductive properties. The salt water then creates an opposing magnetic field. This creates water turbulence.
When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely. These ions are what carry electricity through water with an electric current. In short, salt water can help to produce electricity. While this can be done on a large-scale, let's try a small scale science project to see how it works! (Adult supervision recommended)
Dr. Alhseinat discovered that the magnetic field does more than apply the Lorentz force, which is the electromagnetic force that makes something, such as a wire with an electrical current flowing through, it physically move (this is how electric motors work); it weakens the bonds between the salt molecules in the water. “The salt ions being separated from seawater are actually hydrated ions, which are crystalline salt molecules attached to a certain number of water molecules.
