Magnet Experiments

  1. St. Patrick's Day Science Experiment

    St. Patrick's Day Science Experiment
    St. Patrick’s Day is usually associated with lucky clovers, leprechauns, and gold at the end of rainbows. Unfortunately, gold is not magnetic so it’s more difficult to find even when using a rainbow as a map. What metals are magnetic? Here’s a fun St. Patrick’s Day-themed science experiment you can try to determine what materials have magnetic properties and how they move through different density’s when a magnetic field is applied: Continue reading →
  2. DIY Diamagnetism Experiment

    DIY Diamagnetism Experiment
    Diamagnetism is a magnetic property first discovered in 1778 by Dutch scientist Sebald Justinus Brugmans. He discovered the property while using bismuth and antimony and realized they were repelled by magnetic fields. It wasn’t until 1845 that English scientist Michael Faraday named the property diamagnetism while studying elements and compounds that exhibited negative magnetism, meaning they were pushing away from the magnet. In layman's terms, diamagnetism is a property that every element possesses, which causes a weak repulsion from a magnetic field. In contrast, some elements also possess ferromagnetism and paramagnetism, which causes them to be strongly attracted or repulsed by the magnetic field. To show diamagnetism, you can use a DIY magnet experiment with a common everyday food, grapes, to show small repulsion when exposed to a strong rare earth magnet. This experiment will only work with neodymium magnets because of the strong magnetic field they produce.     Continue reading →

    Magnetic fields are invisible so what can we do to determine where they are and how strong they are? If you don’t have a ferrofluid bottle or magnetic field viewer film on hand, you can create your own magnetic field sensor with this tutorial: Continue reading →
  4. Magnetic Science Experiment

    Magnetic Science Experiment
    Neodymium magnets are not only useful for organizing clutter or making crafts, but also for demonstrating the unique properties of magnetism and magnetic fields. If you’re looking for an easy and fun science experiment, check out this magnetic tutorial for a hollow pyramid with a ring magnet: Continue reading →
  5. DIY Levitating Pen

    DIY Levitating Pen
    Today, people use their keyboards to write more often than they use pens or pencils. If that doesn’t stop you from buying nice new pens, here’s a high-tech way you can display your favorite writing utensil using magnetic levitation: Continue reading →
  6. How To Use Magnetic Field Viewer Film

    How To Use Magnetic Field Viewer Film
    There are many different ways to see magnetic fields even though they are invisible to the naked eye. You can use a compass or iron filings to determine the direction and boundaries of a magnetic field. Or you can use magnetic field viewer film to see the magnetic field lines of magnets. It’s usually used by hobbyists to examine electronics. So, how does it work? Continue reading →
  7. 5 Things To Magnetize With Heat Shrink Tubing

    5 Things To Magnetize With Heat Shrink Tubing
    When you have neodymium magnets the possibilities for innovative DIY crafts and home improvement projects are endless. You can can organize everything more efficiently or hang temporary decorations for fall with magnets. If you add heat shrink tubing to your supply list, there are even more possibilities especially if you want to avoid a gluey mess. Here are five things you can magnetize with heat shrink tubing to make them easily accessible and harder to lose: Continue reading →
  8. DIY Magnetic Rocket Experiment

    DIY Magnetic Rocket Experiment
    Launching a rocket into space is expensive. The current chemical method requires over 800,000 gallons of liquid propellants. On average it costs $450 million per shuttle launch, which is in addition to the cost of the shuttle itself. The Space Shuttle Endeavor cost $1.7 billion. So, as costs continue to rise some scientists and engineers are trying to come up with an alternative launch method. Continue reading →
  9. Magnetic Liquid Body Armor

    Magnetic Liquid Body Armor
    The popular Iron Man movie franchise and comic features a suit of body armor that could make any engineer green with envy. The Iron Man suit, a work of science fiction, seems to be a feat of futuristic engineering not yet possible today. Or is it? Scientists are working on an impenetrable suit of body armor consisting of iron particles and a carrier liquid. This liquid body armor is possible because it contains magnetorheological (MR) fluids. Continue reading →
  10. How To Make A Magnetometer

    How To Make A Magnetometer
    Magnetometers are used to measure the direction of a magnetic field or the magnetization of a magnetic material. They can also be used to measure geomagnetic storms. So, if you missed the aurora sightings from the latest geomagnetic storm you can predict the next ones with your own DIY magnetometer. Continue reading →
