The magnet is indispensable in our modern life. It has many uses and application. You may remember the childhood days when you are spending your whole time in pushing and pulling two magnets and enjoying the fun therein. Apart from the childhood play and fun there are various significant uses that magnets has in home audio to modern medicine.

Magnets in Speakers:

Most of the speakers are engineered with the neodymium Magnets inside paired with a coil that is responsible to turn electric energy into the energy that creates sound. The coil inside the speakers is wrapped in a bobbin which carries the electronic signal that work together with the magnetic field. Thus the voice coil responds to the magnetic energy and moves the speaker cone while compelling the air inside the speaker. As an effect the process creates sound.

Magnets in Compass:

Another imperative use of neodymium Magnets a compass. A compass is a navigational instrument that is helpful in showing directions in the air. It is a small but very useful device which identifies the direction without any outside power. It works with the magnetic field. There is a magnetized needle located at the center of a compass. The needle works with the magnetic force exerted on it in accordance to the planet's magnetic north and magnetic South Pole. Now the professional compasses come with a neodymium block Magnets in place of the needle that is glued beneath a pivoting disk.

Magnets in Maglev:

Maglev is a magnet levitation transportation system. The arrangement is most suited for trains. The technology can be performed with the help of huge amounts of neodymium Magnets.  It does lift and propel the train on very soaring speed. The use of magnet in the process makes the train much quieter and smoother. It works with the amount of the energy derived from the powerful neodymium Magnets which can perform to levitate the train.

Magnets in Magnetic Resonance Imaging:

Magnetic resonance imaging is the best innovation of the medical science in the modern age of medicine to image the insides working aspect of the body in detail. The great magnetic power has been used to magnetize the body's atoms. It does the function through align and realign the bodily atoms in a correct manner. Therefore the scanners can produce detailed images of the body scanned. As it produces 3-D imaging, the severe ailment like cancers, heart issues and brain problems can also be detected and treated through it.
