"India Lacks a Framework to Map Rare-Earth Magnet Dependence"
NdFeB magnet
Neodymium-Iron-Boron permanent magnet with the highest energy product and power-to-weight ratio.
Critical minerals
Minerals essential for economic development and national security, with high supply-chain risk.
Rare earth elements and other critical minerals have become central to India's industrial policy because they are essential inputs for clean-energy technologies, electronics and defence equipment. The Ministry of Mines has notified a list of critical minerals for India, and the government amended the Mines and Minerals (Development and Regulation) Act, 1957 through a 2023 amendment to allow private companies to explore and mine several of these minerals, including rare earths, through competitive auction. To reduce reliance on any single supplier, the government also set up Khanij Bidesh India Ltd (KABIL), a joint venture tasked with acquiring mineral assets overseas, and later launched the National Critical Mineral Mission to widen domestic exploration, processing and recycling capacity. These steps reflect a broader shift in Indian industrial policy toward building capacity in strategic inputs rather than depending entirely on trade.
This push gained urgency after China tightened export controls on rare-earth magnets and materials, exposing how much of the world's clean-energy and electronics manufacturing depends on a small number of Chinese processing facilities. Much like colonial-era India, which was structured by colonial policy into a supplier of raw materials and a consumer of finished industrial goods, a mineral strategy focused only on securing ore risks leaving India as a raw-material exporter unless matching investment builds capability in the processing and manufacturing stages that add real value.
Among permanent magnets, four broad families exist: Ferrite, Alnico, Samarium-Cobalt and Neodymium-Iron-Boron. Neodymium-Iron-Boron (NdFeB) magnets combine the highest commercially available magnetic energy product with a superior power-to-weight ratio, making them the preferred choice for electric-vehicle motors, wind-turbine generators, precision manufacturing equipment, defence systems and consumer electronics. Ferrite, Alnico and Samarium-Cobalt magnets remain in use for specific applications where cost, temperature tolerance or corrosion resistance matter more than raw magnetic strength, but none matches NdFeB's combination of strength and compactness for high-performance uses. …
With reference to India's National Critical Mineral Mission, consider the following statements:
1.It seeks to enhance domestic exploration, mining, processing and recycling capacity for critical minerals.
2.It funds only overseas mineral asset acquisitions and does not cover domestic processing.
3.Rare earth elements fall within the Mission's scope.
Which of the statements given above is/are correct?
Consider the following statements about permanent magnets:
1.Neodymium-Iron-Boron (NdFeB) magnets have the highest commercially available magnetic energy product among permanent magnet types.
2.Ferrite and Alnico magnets have been entirely replaced by NdFeB magnets in industrial use.
3.Samarium-Cobalt magnets are used in applications requiring high magnetic strength.
Which of the statements given above is/are correct?
According to recent assessments of the global rare-earth value chain, India's principal vulnerability regarding critical minerals stems mainly from:
Arrange the following stages of the permanent-magnet value chain in the correct sequence, from the earliest to the final stage:
1.Chemical separation of rare-earth oxides
2.Mining of ore
3.Alloying and magnetic material engineering
4.Geological exploration
