Magnets

By: Franciting

Hi, I've heard that you needed some help with magnets. Well, I have been studying them and I know a lot about them now. I know three topics about them mostly.

1. Magnetic north and south compared to the geographic north and south.

2. What items will or will not attract through.

3. Ways humans use magnets.

I have been working on magnets for about two weeks, so I know what I'm doing.

How would you compare the magnetic and geographic north and south poles? I know a few. One is that they aren't in the same spot, they are about 100 kilometers away from each other. Another is that the map relies on the geographic north and south poles. But something different relies on the magnetic north poles. The compass; the compass is being pulled by the magnetic north pole. The funny thing is, most people think the compass points to the geographic north pole.

What kinds of magnets will or will not attract through? It depends on the kind of magnet it is like iron or steel. I had done an experiment with fourteen different items and five different kinds of magnets. I used a weak kind of magnet called the circle magnet. The items that is couldn't attract through was the wooden ruler, the piece of cardboard, the water, your hand, a piece of fabric, a tin can, some aluminum foil, your shoe, some pattern blocks, a glass jar, a shovel, a clay mug, a plastic bag, and Mr. Swale's  shelf. You might not have noticed but that's all fourteen of  the items. But that's just for one magnet. It depends also on what the items are. Here are two examples of the items that didn't let the magnet attract to through: One is the hand, it failed because it is very thick, and what is in your hand are thick material     like skin, meat, and bone. Another is Mr. Swale's shelf. It was really hard to tell if it was attracting through because it already magnetic. But I knew it wouldn't let the magnet through because it has a magnetic field, and it wants the paper clip and circle magnet to attract to it. Also, on the bottom of the shelf is wood, and it's guarding the shelf like a drawbridge.

What are ways humans use magnets? That's a good question. One way is for hanging up papers and pictures on other items that are magnetic like fridges or lockers. Another way is for experiments, inventions, even essays! A third way is for decoration, just for fun and design! A fourth way is to play with magnets, a hobby that toddlers enjoy! An amazing way that i just learned recently is for curing sick cows, that swallowed bits of hay wire and other scraps that got into their food. The magnet that helps them is called the cow magnet. A veterinarian would feed the magnet to the cow and the wire would stick to the cow and the wire would stick to the magnet and the wire would stick to the magnet and it won't pierce through the cow's intestine. You don't have to take the magnet out because if hay wire and scrap ever get sorted into the cow's stomachs again it'll just stick to the cow magnet.

Like I said, i know magnets pretty well and over the weeks I learned to enjoy them. Now that you know so much about magnets you probably feel like you can learn about the whole world, starting with magnets.
