Electrostatic induction
Electrostatic induction is like when you use your magic wand to move things without really touching them. It happens when you have an object with a magical electric charge nearby another object, and the charge changes the way the electrons move around in the other object.
Let's say you have two magic balloons, one with a positive charge and one with a negative charge. If you put them close together, the electrons in the regular air molecules around them will start to move around too. Some of the electrons will be attracted to the positive balloon, and some will be repelled by the negative balloon. This means that there will be more positive charges on one side of the negative balloon, and more negative charges on one side of the positive balloon.
Now, if you bring a third balloon (without a charge) near the positive balloon, the electrons in the third balloon will start to move too. The positive charge on the positive balloon will attract the electrons in the third balloon, and some will move over to the side closest to the positive balloon. The electrons on the other side of the third balloon will move away, because they're being repelled by the positive charge.
So now you have the third balloon with a temporary charge, even though it never actually touched the balloons with a charge. This is electrostatic induction! It's like using your magic wand to move things by just waving it around. In the same way, you can use electrostatic induction to move around electric charges without actually touching them.
