Some general uses of Magnets

Magnets are the useful element in home appliances in day to day life. If you closely watch you can even make out the use of magnets in different household applications. It is there in every corner of the home starting right from the door latch, refrigerators and even in the toys of your kids. All these are the permanent magnets. Neodymium is the permanent magnets of very strong type. The mechanism used for your washing machine known as electromagnets also possible due to the use Neodymium magnet. Several other electronics appliance such as computer hard drives, Personal video recorders as well as use of credit cards is made with the magnetic principles.

Door Latch:

Often it has been seen that while we leave the door the door, it stay there without closing by its own. So use of magnet can result in closing the door properly with less effort. Most people use magnets for their bathroom medicine cabinets. It is the small Neodymium magnet which keeps the door closed. Same can be applied for draws and cupboards. The magnet has a magnetic field which can work against the force of the metal like steel. Thus using the force it is possible to keep the door closed. Apart from that the same mechanism is also used for the refrigerator doors to be closed. Even in pet doors you can use Neodymium magnets. It is preferable because the magnetic force make the door shut but at the same time it can be opened with a little nudge of your dog or cat.

Motor:

A set of effective Neodymium magnets can make a motor run. The Electric motors gets power from the magnetic field of a pair of magnets. The mechanism here runs with the power of one set of magnet inside the case pulling the other set of Neodymium magnets used in the rotor. This activity results the spin. Apart from this powered by an electric current, motors also use electromagnets mechanism to attract and repel

Speakers:

In homes you can find headphones, Stereo speakers, as well as ear buds use magnets. These magnets are responsible to convert the Electric signals into sound effect. It acts as an amplifier. The vibration and other mechanism can only be possible through the use of strong magnets.

DVR:

The digital video recorder (DVR), runs with the electromagnet mechanism. Here read head both senses magnetic fields and work accordingly. The computer hard drive records the high volume of data on the surface of a spinning metal disc. All these are only possible through the use of magnets.
