When a electromagnet on a crane is powered, all of the electricity flows up. However, it shoukd have been affected by gravity, and not go up at all.
Think of it like this--electrons moving in a circuit is like water moving through a hose. You could pump water up to that crane, right? Electrons in a wire are so much more incredibly lighter than water, so they're that much easier to move against gravity as well.
Gravity is a really weak force. Much weaker than electrostatic forces. Electrons are barely 'aware' of gravity.
