Magnets are like magic! 🧲✨ They stick to some metals because they have a special power called magnetism. Not all metals stick to magnets—only ones like iron, nickel, and cobalt. Try sticking a magnet to your fridge—it works because the fridge has metal inside!
Fun fact: The Earth is like a giant magnet too! That’s why compasses always point north.
Magnets stick to certain metals because of tiny invisible forces called magnetic fields. These fields pull on metals like iron, nickel, and cobalt. The metal has tiny particles inside it that line up with the magnet’s field, making them stick together! 🧲🔗
Not all metals are magnetic—aluminum and copper won’t stick. Magnets have two ends: a north pole and a south pole. Opposite poles attract, while the same poles push away!
Fun fact: The strongest magnet in the world is in hospitals—it’s used in MRI machines to take pictures of your insides!
Magnets attract certain metals due to the alignment of electron spins in atoms. Metals like iron, nickel, and cobalt have unpaired electrons that create tiny magnetic fields. When a magnet comes close, these fields align, creating a strong attraction. This is called ferromagnetism. 🧲⚛️
Other metals (e.g., aluminum) have paired electrons, so they don’t react to magnets. Magnets have dipoles (north and south poles), and their strength depends on their material—neodymium magnets are the strongest!
Fun fact: Scientists think some birds use Earth’s magnetic field to navigate during migration—like a built-in GPS!
