Maglev Train by 10 kilometer Permanent magnets

AI Thread Summary
Building a long permanent magnet for a Maglev train system is technically feasible. The concept involves using a series of permanent magnets arranged to create a magnetic field that can support and propel the train. Advances in materials and engineering could enable the construction of a 10-kilometer-long permanent magnet track. However, practical challenges such as cost, maintenance, and magnetic field uniformity must be addressed. Overall, the idea presents an innovative approach to Maglev technology.

I want know that can we build a long Permanent magnet for a Maglev way ?

Please say that its possible ?

(i attached one picture , with that you can understand that what is my question and what is a long Maglev way by a Permanent magnet)

Thread 'What happens if shielded cable has a short to the shield?'

While I was rolling out a shielded cable, a though came to my mind - what happens to the current flow in the cable if there came a short between the wire and the shield in both ends of the cable? For simplicity, lets assume a 1-wire copper wire wrapped in an aluminum shield. The wire and the shield has the same cross section area. There are insulating material between them, and in both ends there is a short between them. My first thought, the total resistance of the cable would be reduced...

Thread 'How might electronics be different if AC voltage was 72V at 45 Hz?'

Hey guys. I have a question related to electricity and alternating current. Say an alien fictional society developed electricity, and settled on a standard like 73V AC current at 46 Hz. How would appliances be designed, and what impact would the lower frequency and voltage have on transformers, wiring, TVs, computers, LEDs, motors, and heating, assuming the laws of physics and technology are the same as on Earth?

Thread 'Why does the amperage go real high if there is a low voltage short?'

I used to be an HVAC technician. One time I had a service call in which there was no power to the thermostat. The thermostat did not have power because the fuse in the air handler was blown. The fuse in the air handler was blown because there was a low voltage short. The rubber coating on one of the thermostat wires was chewed off by a rodent. The exposed metal in the thermostat wire was touching the metal cabinet of the air handler. This was a low voltage short. This low voltage...
