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)

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
