You sketch a water molecule and show a partial positive charge on the two Hydrogen atoms and a partial negative charge on the oxygen atom.
        
             
        
        
        
Explanation:
A magnetic field can be created by running electricity through a wire. All magnetic fields are created by moving charged particles. Even the magnet on your fridge is magnetic because it contains electrons that are constantly moving around inside 
 
        
             
        
        
        
               ( 3 yr) · (186,282.397 mile/s) · (86,400 s/day) · (365 day/yr)
           =  (3 · 186,282.397 · 86,400 · 365)  mile
           =      1.762380502 x 10¹³  miles
           =      1.8 x 10¹³  miles    (rounded to the nearest trillion miles)
        
             
        
        
        
Sound intensity = 1/(r^2)
That is Sound intensity is indirectly proportional to  the distance. Therefore, sound becomes 9 times less intense.
