Tackle them by being strongly attracted to them.

You can't talk about just magnetism, electricity and magnetism are different facets of the same thing. And Maxwell's EM equations are the authoritative desription for the behavior of EM. There's several forms those EM equations can take depending on your mathematical sophistication.

If you're in high school, the best way to understand magnetism is the right hand rule. Take the direction a charged particle is moving in, and point the fingers of your right hand in that direction. Curl your fingers towards the direction of the magnetic field line the particle is crossing. Stick your thumb straight out, that's the direction of the force the particle feels. If the particle is negatively charged, the force will be opposite to the direction of your thumb.

The vector formula is q(v x B).

So how do permanent magnets attract and repel each other? Pretend there's a permanent electric current rotating inside each magnet. You have charges moving in circles, and you have magnetic field lines from the other magnet. From that you can figure out the forces involved.

It's extremely difficult to type those equations here.
