* **bullet trains: ** bullet trains are also called Maglev trains.. ****as they work with the help of powerful electromagnets which make them high speed trains ,, electromagnets are attached to metal lining of track large magnets are present inside the train they work on the principal that like poles repel and unlike poles attract.. **circuit breakers: ** it is a device which cuts the power when when there is too much current flowing through the circuits,, they are also called fuses,, they work with the help of electromagnet ,, to cut the circuit and rejoin... *
The magnetic effect of current is utilized in both bullet trains and circuit breakers. In bullet trains, magnetic braking is achieved through eddy currents generated when the train moves into a magnetic field, creating a force that slows the train down without direct friction. Circuit breakers, on the other hand, use electromagnets to interrupt circuit flow when current reaches unsafe levels. As current increases, the electromagnet strengthens, eventually pulling an iron catch lever that disconnects the contacts and stops the electricity flow. The magnetic effect is also implicated in the force between wires, which is significant enough to define the ampere and explain why attempting to break large currents can lead to damage in large circuit breakers.
Bullet trains use electromagnets to levitate and propel the train, allowing for high speeds through magnetic repulsion and attraction. Circuit breakers automatically cut off excessive current using electromagnets to prevent electrical overloads and potential hazards. Both systems showcase the practical benefits of electromagnetism in modern technology.
