What are the two poles of a magnet? What happened when you placed the magnet next to the copper? What happened when you placed the magnet next to the iron? What is the relationship between distance and magnetic attraction? Give three examples from your life of magnetic force. @Secret-Ninja

Q1: They are the "north" and "south" poles. Q2: Nothing, copper isn't ferromagnetic so magnets aren't attracted to it. Q3: The magnet is attracted to it and pulls it to it. Q4: The magnetic field gets weaker the further away because of the inverse-square law: In physics, an inverse-square law is any physical law stating that some physical quantity or strength is inversely proportional to the square of the distance from the source of that physical quantity. So, they are inversely related. as the distance increases the magnetic attraction decreases and when the distance decreases the magnetic attraction increases.

Some examples are when you use a magnet to put a note on a fridge. Also when teachers use magnets to hold things up on dry erase boards.

Compasses also use the earth's magnetic fields to point North.
