That is one of the questions where you say, "that is just how it is.".
The true answer is that they aren't two different things but two expressions of one thing: electromagnetism. There is truly only one single force present, but if you look at it from one side it looks like electrical forces and fields and from the other side it looks like magnetic forces and fields. The sides are always perpendicular because you have to be perpendicularly looking to only see one aspect of the electromagnetic force and not the other. You can in fact look at it from a skewed angle and see both.
So I don't have a better answer than that for an ELI5 answer. The electric field is like looking at the electromagnetic force from the front and the magnetic force is like looking at it from the side. If you can see some of the front you aren't looking straight at the side and if you can see some of the side you aren't looking straight at the front. In our dimensional space the perspectives have to be perfectly perpendicular to only see one aspect at a time.
