The correct answer is North & South poles attract each other. This is because opposites attract. If it were a north & north pole they'd repel each other, same if it were a south & south pole. This is because each magnetic field has a way of attracting two opposite poles (north to south, south to north).
<span>The reason that things look wavy in the heat over a hot grill or stove is that the air temperature is not stable. Hot air naturally rises, so as air comes off the hot surface, it rises for a bit before rapidly cooling and sinking to be heated again. This constant mixing of hot and cool air produces vibration. This vibration affects how we see the light moving through the air, making it look wavy.</span>
