Differences between electrostatic and magnetic interactions

While doing investigation 2, I discovered some differences between electrostatic effects and magnetic effects. Firstly, I found out that magnetic interactions can be stronger. For example, in one of the tests we did, I saw that a magnetic interaction can still take place even with a paper acting as a barrier. However, electrostatic interactions don't take place if something is blocking the way. In addition, I also saw that water doesn't have an effect on magnetic attractions. However, inside the water, the electrostatic interactions did not take place. This further adds to the fact that magnetic attractions are stronger.
