Case Study on Advance Course NEET-AIIMS Physics Syllabus Magnetic effects of current and Magnetism
Case Study: Magnetic Levitation
One fascinating application of the principles of magnetic effects of current and magnetism is magnetic levitation. Let’s consider a case study on how magnetic levitation is used in various real-world applications.
Case Study: Maglev Trains
Maglev trains, short for magnetic levitation trains, are a prime example of the practical implementation of magnetic effects of current and magnetism. These trains utilize magnetic forces to levitate above the tracks and move at high speeds without any physical contact with the ground.
The basic principle behind maglev trains involves the interaction between superconducting magnets and electromagnetic coils. The train’s undercarriage contains superconducting magnets that generate a strong magnetic field. Along the tracks, electromagnetic coils are placed, which produce a changing magnetic field as the train moves.
As per Faraday’s law of electromagnetic induction, the changing magnetic field induces an electric current in the coils. This induced current creates an opposing magnetic field, resulting in repulsion between the coils and magnets. This repulsive force counteracts the gravitational force, enabling the train to float above the tracks.
To propel the train, additional propulsion magnets are installed on the train’s underside. These magnets interact with the electromagnetic coils on the tracks, generating forward or backward forces to move the train. The absence of friction between the train and the tracks allows for efficient and smooth travel at high speeds.
Maglev trains offer several advantages over conventional trains. They can achieve incredibly high speeds due to the absence of friction, resulting in reduced travel times. The absence of physical contact between the train and tracks leads to minimal wear and tear, reducing maintenance requirements. Moreover, maglev trains produce less noise and vibrations compared to traditional trains.
Countries like Japan, China, and Germany have successfully implemented maglev train systems, revolutionizing transportation. For instance, the Shanghai Maglev Train in China can reach speeds of up to 430 km/h (267 mph), making it one of the fastest commercial trains in the world.
This case study demonstrates how the understanding of magnetic effects of current and magnetism has been applied to develop innovative transportation systems like maglev trains. It showcases the practical implications of these concepts and their contribution to advancements in engineering and technology.
