The magnetic field around a current-carrying wire is proportional to the current and proportional to the distance from the wire. If the current triples while the distance doubles, the strength of the magnetic field increases by times.

As the energy of a wave moves through the water what happens to the water particles them selves

The law of conservation of energy is a statement that : energy must be conserved and you are breaking a law if you waste energy. the total amount of energy is constant for a closed system. the supply of energy is limited so we must conserve.
