Most modern washing machines today have sensors that will determine how much dirty laundry is inside the drum. This will then allow the washer to fill the drum with just enough water to clean the dirty clothes. There are also dirt and moisture sensors in washers. It senses dirt in clothes to determine the right amount of cleaning time.

The answer is both yes and no.It actually depends on the kind of washing machine in question.The problem is the motion.A washing machine need some kind of an engine or motor in order to move the cloths back and forth. This can of course be done manually.If we rule out manual washing machines, and also only count in electrical ones then these can be made in two different ways.The motor causing the tumbling or the motion in the washing machine can be made with both permanent magnets like NeoDym, or with purely electrical pulses creating strong electromagnetic fields.Most motors in washing machines made today are made without magnets. It is cheaper to make purely electrical motors where the electricity provides the magnetic fields needed. By electronically rotate the magnetic field around the axis, this will force the motion of the motor. It would use less electricity to make the motors with NeoDym magnets but it would also cost more to produce.As a conclusion: We can not make an electrical washing machine that operate without magnetic fields, but magnetic fields does not have to be made by magnets.

There is a difference between generic and brand name washing machines, and that difference lies mostly within the realm of price. Even though you may believe that a brand name will automatically be of higher quality, you would be surprised at how comparable in quality generic washing machines are to brand name ones. The major difference is the price, making generics much more desirable for the vast majority of people shopping for washing machines today.
The first practical helicopter was invented in the 1930's. Following this, like all machines, it evolved bit by bit to become what it is today. - Very few machines were "invented" as such, almost all came from different designers adding improved parts.The helicopter is still in 'evolution' and improvements to it's rotor head, transmission and blades are underway as I write.
Australia would have seen a similar unit today's fax machine sometime in the 60s. Before then there may have been services similar to a fascimile service but not compatible with today's fax machines.
A common list of the six "basic machines" is:1. The Wheel and Axle2. The Pulley3. The Wedge4. The Inclined Plane5. The Screw6. The Lever.All of these machines were invented in ancient times. All of them form the basis of all machinery used today.

Washing machines have totally revolutionized the way the family does laundry. Decades ago, women were forced to scrub their families laundry on wash boards with boiling water. The work was grueling and back breaking. In addition, it was time consuming. Our modern culture has come a long way from those days. Presently, washing machines are state of the art. Consumers have a large variety to choose from in the stores. A person can get all of the bells and whistles for the right amount of money. Do you want the dry cleaner look? This is possible with the new technology installed in washing machines of today. Although style and features are important when selecting a machine, the consumer should also consider other things. First, how much laundry will the machine need to hold. This is a big part of the decision process. Washing machines are made with different capacities. If too large of a load is washed, it can tear up the washing machine. Another consideration is the type of clothing. People should not put heavy comforters and bed covers in cheaply made washing machines. These machines are simply not built to handle this. Consumers also have to be concerned with their budget. There are many options available; however, it should fall within your budget. There are numerous brands offered on the market. It is best to study the track record of specific companies. Some people still have washing machines from thirty years ago. Certain brand names are made to truly last for decades. Newer machines these days do not tend to last as long, so the consumer should make an educated purchase. In addition, the warranty is an important consideration. It does add an extra expense, but there is some peace of mind associated with having this coverage. A good warranty will cover the repair and/or replacement of a washing machine if the machine fails within a certain time frame. Each warranty has specific requirements, so the consumer should take into consideration these requirements. Failure to adhere to certain standards could forfeit the warranty coverage. In conclusion, your washing machine is an important appliance in the home. Thus, great care should be taken when selecting washing machines.
