In which home appliances magnets can be found and how does a dc motor work
Answers
Answer:
Flick a switch and get instant power—how our ancestors would have loved electric motors! You can find them in everything from electric trains to remote-controlled cars—and you might be surprised how common they are. How many electric motors are there in the room with you right now? There are probably two in your computer for starters, one spinning your hard drive around and another one powering the cooling fan. If you're sitting in a bedroom, you'll find motors in hair dryers and many toys; in the bathroom, they're in extractor fans, and electric shavers; in the kitchen, motors are in just about every appliance from clothes washing machines and dishwashers to coffee grinders, microwaves, and electric can openers. Electric motors have proved themselves to be among the greatest inventions of all time. Let's pull some apart and find out how they work!
In motor we can find magnet.
HOW DOES MOTOR WORK:
The primary principle that makes a DC motor work is based on how magnets react to each other: like magnetic poles repel and unlike magnetic poles attract. When you look at a DC motor, you will see a coil of wire and a horseshoe magnet as part of its basic components. In class 7 we would have studied that when we roll a copper wire around nail and pass electric current then it acts as an electromagnet. Every time an electric current run through the coil, an electromagnetic field is generated and aligned to the center of the coil. As you switch the current on or off, the magnetic field is also turned on or off.
