Induction heater
An induction heater is a really cool device that uses a special kind of magnetism to heat up metal objects without ever touching them. It's like magic!
Okay, let's break it down. First, you have to understand what magnetism is. You know how magnets can stick to your fridge? Well, that's because they have a special force that pulls them towards metal things. This force is called magnetism.
Now, let's talk about how the induction heater works. The induction heater has a special wire coil inside it that creates a really strong magnetism when it's turned on. This magnetism makes electricity flow through metal objects that are placed near it.
When electricity flows through the metal object, it creates something called "electrical resistance". This is kind of like when you try to run through water - it's harder to move because the water is in your way. In the same way, the electrical resistance makes it harder for the electricity to flow through the metal object.
This resistance creates heat! The metal object starts to get really hot, even though it's not touching the induction heater. So, the induction heater can be used to heat up things like metal rods, nuts, bolts, and other metal parts that need to be heated up for things like welding or forging.
Pretty cool, huh? The induction heater is a very useful tool for people who work with metal, and it's all thanks to a special kind of magnetism and electrical resistance.
