Magnets have enchanted the human beings since the ancient Greeks discovered the strange material which was called as lodestone. The mysterious force between the two pieces of this material remained unexplained for centuries. The modern science explains the phenomenon of the working of the force between the two pieces of this material. The secret of making super strong magnets is not apparent even today. It is critical to understand how to do this because modern techniques like clean and effective electrical power generation depends on it. Greener electrical power is delivered if the customer gets stronger lighter magnets. Most of the people outside the scientific community do not know the working of the magnets.
The recognition that the electric force between electrical charges and the force between magnets were two different representations of the same thing was one of the important moments in modern science. The concept that electrical current could generate magnetic forces and magnetic forces could generate electrical current form the basis of many inventions and devices which is seen today. For instance, generators apply this principle to convert mechanical energy - the energy of moving objects - into electrical energy, the energy which drives all modern electrical devices. The process can be reversed to convert the electrical energy in to mechanical energy as well which is amazing and this is the working principle of the electric motor.
Therefore, magnets have various vital industrial uses and other applications. The iron neodymium boron magnets are the stronger magnets which are used for commercial development. These magnets possess higher strength for their sizes than other types of magnets. The fact that neodymium is a “rare-earth” element is the main drawback to the wide industrial use of these magnets. Since the deposits of this material are very rare, they are extremely costly. This threatens the widespread deployment of applications like wind-powered turbines, which depend on lightweight but strong magnets for the most effective power generation.
The magnets are widely used in industrial motors. In motors, the electric current spins the magnet which in turn moves the drive train of the motor. Electric powered vehicles are increasingly becoming popular in the market. The magnets that can move these vehicles without adding extra weight will be the most important factor to decide the working of the electrically powered transportation in future.
Strong magnets have important role to play in most important industries of the future. Research has been undertaken to search better magnets which have the same strength as the current state of the art magnets but use more common and cheaper materials. The knowledge on the working of these materials has progressed substantially since ancient times but there are many secrets that need to be explored from this loadstone.
