Devices that allow frictionless travel have been present throughout science fiction. At current transportation using magnetism is limited to the same principles that allow Maglev Trains to function.
No, a frictionless surface cannot exert a normal force because the normal force is a force exerted perpendicular to the contact surface and is necessary to counteract the force of gravity or any other downward force. Without friction, there is no need for a normal force to counteract any horizontal force component.
yes
slickness, smoothness, frictionless
No a train does not float in the air, no train does.
In theoretical physics, a frictionless surface is a plane in which no forces oppose motion, resulting in no energy loss due to friction. However, in the real world, achieving truly frictionless surfaces is practically unattainable due to the presence of various microscopic imperfections and forces at play.
Everywhere! Frictionless surfaces do not exist.
it is the act of without friction.

no there is not a magnetic train in India

Frictionless data means sharing data though social media sources. It a cheap way of sharing data and allows for massive amounts of data to be shared easily.
