Exhibit Summary
Mutual induction coil is a Interactive interactive exhibit in the Electromagnetism category, designed for science centers, children’s museums, discovery centers, STEM learning centers and family entertainment centers. Built as a hands-on, mechanical & electromechanical display, it turns an abstract scientific concept into direct, interactive visitor exploration, and is engineered for durable, low-maintenance, high-traffic gallery use.
Scientific Principle
aims to let the audience grasp the definition, basic principles and applications of mutual induction coil.
Operation
When the current in one coil changes, an induced electromotive force is generated in another adjacent coil, which is called mutual inductance. Mutual inductance is a common electromagnetic induction phenomenon that not only occurs between two coils wound on the same iron core, but also can occur between any two circuits that are close to each other. For example, when two inductor coils are close to each other, the change in the magnetic field of one inductor coil will affect the other inductor coil. This effect is called mutual inductance. The size of the mutual inductance depends on the degree of coupling between the self-inductance of the inductor coil and the two inductor coils. The component made using this concept is called a transformer. The mutual induction coil display has three sets of coils. The middle set of coils is energized and the two adjacent sets of coils are de-energized. When the button is pressed and the AC power is turned on, you can view that the light bulbs in the middle of the two sets of coils next to it will light up. But their brightness is different. The coil with a slightly brighter bulb has more turns, while the one next to it has a relatively smaller number of turns. The reason for this is because of mutual inductance. When the current of the middle coil changes, the two groups of coils next to it will produce an induced electromotive force. This induced electromotive force is related to its number of turns. This is the mutual inductance. It has a very important application in our industry. When we press the DC button, there will be no corresponding phenomenon. When the current in one coil changes, an induced electromotive force is generated in another adjacent coil, which is called mutual inductance. Mutual inductance is a common electromagnetic induction phenomenon that not only occurs between two coils wound on the same iron core, but also can occur between any two circuits that are close to each other.
