Magnet Experiments

Magnets make music possible. How? Magnets are an important component of speakers and headphones, as they convert electrical energy into sound energy. Magnets transmit the sound energy through the “cone” of the speaker. This description isn’t as complex as actual sound design, but it gives you a brief idea of how magnets play a role in sound transmission. Continue reading →

As magnet enthusiasts, we read a lot about all things magnetic—from influential people making magnetic discoveries and magnets in technology to how magnetism functions in space! We recently came across a great way to combine our interests: a do-it-yourself backyard magnetic geodesic planetarium. Continue reading →

Temperature affects a lot of things, and magnets surely are no different. Extreme hot and cold temperatures can destabilize the balance between temperature and magnetic domains affecting the strength. But what is the threshold of temperatures that are beneficial versus which ones are weakening?  Try this science experiment to find out how temperature affects magnet strength! Continue reading →

Explaining the science of magnets to students can be difficult. Hearing the words come out of a teacher’s mouth is one thing but actually seeing the way magnets interact with each other and other materials can really help drive the point home. These simple experiments with magnets will exhibit how magnets work while still keeping students’ attention. Continue reading →

After a long and enjoyable summer, it can be hard for both you and your students to get back into a solid routine. Not to mention, the work you put into classroom setup and creating numerous lesson plans at the beginning of each school year can exhaust you quickly. Instead of allowing your work to become a daunting task, try adding some demonstrations that can liven up the classroom and help ease the transition from summer to school year. Below outlines a science demonstration using magnets and other ingredients that you can add to your lesson plans! Continue reading →

Inside the classroom, the magic of magnetism can be quickly lost to complicated charts and technical assignments. But there’s no shortage of compelling projects you can complete with your students to explain and demonstrate how magnets work without ruining the fun. Continue reading →

The world of magnetism is downright vast. From astrophysics to arts and crafts, it plays a large role in many areas of life. What we don’t always hear about is the science behind magnetism—the ins and outs of what makes it work and how these theories can be applied. Continue reading →

Many tech developers, including Elon Musk, are working on magnetic hyperloop trains. These mass-transit vehicles would be capable of traveling at unseen speeds and totally revolutionize the way many people commute and travel. Continue reading →

If you’ve ever used ferrofluid for a science experiment or project, you know it can get everywhere. While it’s one of the coolest magnetic products available, it’s extremely messy and difficult to clean. Here are some tips to help you clean ferrofluid residue off your work surface so you’re prepared for your next experiment. Continue reading →

The saying ‘bigger is better’ has taken the nation by storm, whether it’s describing the size of your phone or your television. But for the people over at Physics Girl, they’ve taken a liking to the exact opposite of that perspective, shrinking. Now you may remember “Honey, I Shrunk The Kids” where an inventor’s shrink ray miniaturized his children, but this shrinking isn’t movie magic. Using a capacitor, a coil and some electricity they are able to actually shrink a quarter to a notably smaller size. Although it isn’t truly shrinking, but more compressing, it gives the illusion that the quarter has been shrunk down. Continue reading →
