Question

explain how a maglev train provides evidence that magnetic fields can apply forces between objects that do not touch.

Answer 1

A maglev train is a train that floats above a track using magnetic levitation. This means that there is no physical contact between the train and the track, and the train is able to move smoothly and efficiently.

Magnetic levitation is possible because of the repulsive force that exists between two magnets of the same polarity. When the magnets in the train are aligned in the same direction as the magnets in the track, they repel each other, causing the train to float above the track.

The fact that a maglev train can float above a track without touching it provides evidence that magnetic fields can apply forces between objects that do not touch. This is because the magnetic field of the train is able to interact with the magnetic field of the track, even though the two objects are not physically touching.

Maglev trains are a practical application of the principle of magnetic levitation. They are used in a number of countries around the world, and they offer a number of advantages over traditional trains, including:

They are more energy-efficient

They are quieter

They have a smoother ride

They are faster

Maglev trains are a promising technology for the future of transportation. They offer a number of advantages over traditional trains, and they have the potential to revolutionize the way we travel.

Answer 2

Magnetic fields can apply forces forces by the interaction between magnets and magnetic material

Step-by-step explanation:

In a maglev train is made up of a train cart with superconducting magnets beneath, which is then mounted above specially designed maglev guideway. The non-contact motion of the train by the magnets is due to interaction between the magnetic field of the train with metallic loops in the guideway thereby inducing an opposing magnetic field in the loop which serve the purposes of 1. Keeping the train 5 inches above the guideway, 2. Maintaining horizontal stability and 3. Movement of the train through alternating the attractive and repulsive forces such that the resultant effect is the net movement of the train.
