How do electric motors?
Electric motors work by placing the opposite poles of an electromagnet that is fixed onto a spindle or axle near to either end of a fixed magnet. This causes the moving electromagnet to spin slightly then come to a halt. If, at the correct time, the battery or other source of current feeding the electromagnet is flipped - thus reversing the polarity - it will complete another slight spin in the same direction. The repitition of this action provides the movement required to make the spindle of the motor rotate.Other answersWhat makes a motor turn is based on the fact that magnetic fields produce physical force that can move things. If you have ever played with magnets you have seen this in action as you use one magnet to attract another magnet or force it to move without touching it, depending on how you line up their poles.All magnets have a north pole and a south pole. Like poles repel each other and unlike poles attract each other.So, in a motor, electricity is used to create magnetic fields that oppose each other and cause something to move, which happens to the motor's rotating part, called the "rotor".On the rotor there are loops of wiring - called "windings" - that have an opposing magnetic field to a magnetic field produced in the housing of the motor that does not move, which is called the "stator". Its magnetic field is produced either, in the case of a very small motors, by permanent magnets or, for most other sizes of electric motor, by loops of wiring called"field windings".It is the repelling action of the opposing magnetic fields which causes the rotor to turn inside the stator.In heavy electric motors having field windings, big problems can arise from excessive heat buildup - including a high risk of the motor's windings and/or its power input cables catching on fire - if something ever prevents the rotor from turning whilst it is still being supplied with electricity. If properly-sized circuit breakers are not installed to give the motor adequate overcurrent protection, any general overloading of the motor or siezed rotor shaft bearings can easily cause such problems.For more information please click on the Related Linkbelow.Electric motors convert electrical energy to mechanical energy.Inside the cover of any electric motor there are 2 kinds of magnets:One does not move and is called the "stator". On some kinds of electric motors the stator can be a permanent magnet and on others it can be an electromagnet.The other kind of magnet is called the "rotor" because it rotates inside the stator. The rotor is always an electro-magnet and when you give it electricity, its copper coils make its metal pieces (which are in the middle of the coils) magnetic.
Who made or makes U.S. Navy ships brass bells?
The C.S. Bell Foundry in Ohio has supplied the U.S. Navy's ship's bells since WWII, though they're not brass; they're a metal alloy.The Bell Foundry primarily is a provider of agricultural mills; the history of how they got into making bells out of an alloy in WWII is pretty interesting, and begins with the fact that brass was a rare commodity during WWII.The link to the story is below.

Is it true that Catholics must not believe in evolution?
It depends on the individuals thought, some people do believe God created through evolution, and some people believe God created everything one by one using clay. But the Catholic Church doesn't say there is no evolution. A lot of Catholics believe that God made all things using evolution. But science itself cannot explain how life originated in the first place, and why we are more intelligent than other animals. The book of Genesis should not be taken 100% literally. For example, the book says that God created the world in 6 days, but the second book of Peter Chapter 3 verse 8 says "With the Lord one day is like a thousand years". When God was creating the universe, before he made night and day, there were no days to start with! The bible does not contradict with the evolution theory nor does it contradict with science.
