Maglev trains: A maglev train is a high-speed vehicle that uses magnetic levitation to float, move, and stop without touching the ground+ It rely on electromagnetic suspension (EMS) and electrodynamic suspension (EDS)+ Working – Floating (Levitation) – Strong magnets on the train and track push or pull the train up so it hovers a few centimeters in the air+ Moving (Propulsion) – Electricity sent through the track creates a magnetic wave that pulls and pushes the train forward very fast+ No Friction – Because the train does not touch the track, there is no wheel wear or rolling resistance, allowing for smooth, quiet, and rapid travel.

Virtual Magnet Technology: Developed by Bengaluru startup Vimag Labs+ It claims to eliminate the need for rare-earth elements in electric vehicles (EVs)+ Traditional EVs use Permanent Magnet Synchronous Motors (PMSMs), which embed physical rare-earth magnets (like neodymium) into the rotor to create a magnetic field+ Vimag Labs replaces physical permanent magnets with copper coils+ Mechanism – Using "Virtual Magnet Synchronous Motor" (VMSM) architecture, the company uses power electronics and software algorithms to dynamically simulate and regulate a magnetic field in real time.

Bank’s credit-deposit ratio: Indian banks’ credit deposit (CD) ratio stood at a 62-year high of 82.6% in the first quarter (Q1) of fiscal 2027 as loans grew faster than deposits, as per data of Centre for Monitoring Indian Economy (CMIE)+ Over the last 5 years, banks had excess investments on their balance sheet, which they have redeployed into loans+ So optically, the loan book is growing faster and the investment book is growing slower, therefore the CD ratio looks higher+ Second, the bank's capital is at an all-time high, giving it greater capacity to support lending and absorb losses.
