Fruit & Magnetism Neodymium Magnet Experiment, Video, Embedded
Hello, everyone! This is the last post about the magnet experiment in this stage. If you haven’t read our previous articles of the series, please click here. You can also subscribe to our Youtube channel to see any updates. Today’s experiment involves everyone’s 2 favorite things: fruit and magnets!
Let’s get started.
The materials used in this experiment are: a wooden stick, a wire, two grapes, two apples of similar size and a super-strong neodymium ring magnet. The magnetic force of the magnet directly affects the probability of success of this experiment. The stronger the magnet, the more obvious the effect of the experiment.
First, insert a grape at either end of a wooden stick. Then, use a wire to lift the middle of the stick while keeping the ends balanced with one another.
If you approach either flying grape with a magnet, you will find that the poor fruit tries to roll out of its way.
That’s weird. Does it work with larger fruit? Let’s try some apples and see what happens.
To explain this phenomenon, we should understand that many kinds of fruit are filled with lots of water and mild acids. This allows them to conduct electricity. When a magnet approaches, an electric current is created inside the fruit and that current creates its own magnetic field. The opposition of the two fields pushes the fruit away and rotates the grapes and apples around your axis.
