Magnet Experiments

  1. 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.

  2. 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 →
  3. Magnet Experiment: The Levitating PaperClip

    Magnet Experiment: The Levitating PaperClip
    Magnets can do some amazing things -- like accelerate a train at speeds over 300 mph or power a MRI to look through the human body. However, sometimes its just fun to conduct experiments with them. One interesting experiment to do is to make a paperclip levitate, or seem to float in midair. The experiment is about as simple as it gets, and you can do it with everyday items that you probably have laying around your house. Here’s how you can do it. Continue reading →
  4. Repelling Magnets Experiment

    Repelling Magnets Experiment
    Every permanent magnet has a north pole and a south pole. Even if you cut a magnet in half, the two remaining pieces will have a north and south pole. And if you know anything about magnetism, you know that opposites attract. The north pole and south pole of two magnets will pull towards each other, whereas two similar poles will repel each other. Magnetic attraction and repulsion are perhaps the simplest and most well-known properties of magnets. In this experiment, we’re creating a device that shows how magnetic repulsion works and makes learning about it fun. Continue reading →
  5. How to Go Fishing With Magnets

    How to Go Fishing With Magnets
    Magnet fishing is more like going treasure hunting in the water than it is like actual fishing. In other words, you won’t catch any fish with this method, unless they are made completely of iron or some other strongly magnetic material. Some treasure hunters throw magnets in lakes and other water ways to attract magnetic metals and pull them up. The hope is that something valuable will surface, but often miscellaneous items like bottle caps and keys are found as well. In fact, strong lifting magnets called magnet retrieval tools are specially designed to retrieve items that are lost at the bottom of bodies of water. However, if you simply wanted to try out magnet fishing and are not looking to retrieve larger, heavier items from the water, you can easily create your own magnet fishing tool. Continue reading →
  6. Recreate Michael Faraday’s Magnetic Experiment

    Recreate Michael Faraday’s Magnetic Experiment
    In the 1800s, a scientist named Michael Faraday made significant contributions to the study of electricity, magnetism and chemistry. One of his most influential contributions was the discovery of electromagnetic induction. Electromagnetic induction is when an electric current is induced. It occurs when a conductor is placed in the presence of a changing magnetic field. You can recreate Faraday’s electromagnetic induction experiment with the instructions below. Continue reading →
  7. Magnetizing Objects with a Bar Magnet

    Magnetizing Objects with a Bar Magnet
    Is it possible to give objects that are not magnets the power of magnetism? That is the question that we are putting to the test in this magnet experiment! Read on to see how a magnet can turn a regular piece of steel or other metal into a magnet. Continue reading →
  8. Make a Dancing Heart with Electromagnetism

    Make a Dancing Heart with Electromagnetism
    Homopolar motors are the simplest forms of motors. They can be built with three simple materials, but their designs can be a little more creative. For instance, you can make spiralling or heart shapes dance with the energy that the motor generates. Since it is close to Valentine’s Day, you can try out this fun science experiment that explores how electricity and magnetism come together and forms electromagnetism. Continue reading →

  10. Spooky Science Experiments for Halloween

    Spooky Science Experiments for Halloween
    From Frankenstein to ghost hunting, science has long been referenced in Halloween stories. Although the science behind the spooky stories is sometimes flawed, we can’t help but admire the creative efforts of storytellers. Therefore, in the spirit of Halloween, we have put together some of the spookiest science experiment ideas that are perfect for teaching science while still  having scary fun. Continue reading →
