So I was surprised to notice that my plastic shopping bag was able to actually push and pull tap water significantly far with its electrostatic force. But when I put a magnet near the water nothing happened. What makes the electrostatic force so different from magnetic force; isn't it just two kinds of the same force (electromagnetic force)? I know the basics about the properties of water (atomic structure, polarity, intermolecular forces [such as hydrogen bonding] that cause adhesiveness and cohesiveness in the water, etc) and electrostatic force (and electromagnetic force which is perpendicular to moving charges). None of my basic knowledge even comes close to explain what pushes and pulls the water and why that doesn't happen with magnetism.
