I’m Ken Kuwako, a Science Trainer. Every day is an experiment! How do you teach students about the relationship between electric current and magnetic fields? There are quite a few rules to remember, such as the “right-hand screw rule” and “Fleming’s left-hand rule,” but helping students actually experience the presence of an invisible magnetic field […]

I’m Ken Kuwako, a science trainer. Every day is an experiment! The smartphone you hold in your hands every day is hiding several tiny “magnets” inside its slim body. Did you know that? In this experiment, we’ll sprinkle some handy MagChip over a smartphone instead of iron filings and reveal the invisible magnetic fields hiding […]

I’m Ken Kuwako, a Science Trainer. Every day is an experiment. The “magnetic field” that forms around magnets and electric currents is an invisible concept, which can make it difficult for students to visualize. In class, I explain things like, “Magnetic field lines run from the north pole to the south pole,” and “The direction […]

I’m Science Trainer Ken Kuwako. Every day is an experiment! When you were a child, didn’t you ever wonder about this? This time, I’d like to unravel that mystery using a “gyro wheel” and explore the hidden power of rotation that we can’t see with our eyes. Once you actually experience it with your own […]

I’m Ken Kuwako, your Science Trainer. Every day is an experiment! Have you ever noticed the advertising magnet sheets stuck to your refrigerator—those thin magnets from water-leak repair companies and other businesses? They may look like nothing more than simple promotional items, but hidden inside these thin sheets is a surprisingly clever magnetic structure. When […]
