Context
India is strengthening its critical-mineral strategy, but a recent NCAER analysis highlights a deeper problem: the country still lacks a clear picture of where dependence exists across the permanent-magnet value chain.
The concern became sharper after China’s April 2025 export controls on certain rare-earth materials used in high-performance magnets, exposing vulnerabilities in downstream manufacturing.
What Are Permanent Magnets?
A permanent magnet retains its magnetic field without continuous external electricity.
Major types include:
- Ferrite — low-cost and widely used;
- Alnico — aluminium-nickel-cobalt based;
- Samarium-Cobalt — strong and heat resistant;
- Neodymium-Iron-Boron (NdFeB) — among the strongest commercially used magnets.
NdFeB magnets are important for EV motors, wind turbines, industrial motors, electronics, robotics, aerospace and defence.
India’s estimated demand for rare-earth permanent magnets may reach 8,220 tonnes annually by 2030.
The Magnet Value Chain
Permanent-magnet security extends beyond mining:
Mining → Separation → Rare-earth oxides → Metals → Alloys → Finished magnets → End-use products
India has upstream capability in mining, separation and oxide refining, but official assessments identify an industrial-scale gap in:
Oxide → Metal → Alloy → Magnet conversion
India currently imports its sintered NdFeB magnet requirement.
Why Does It Matter?
- Systemic Manufacturing Dependence
Magnets are small components but essential to motors, generators and precision systems. A shortage can therefore disrupt much larger manufacturing chains.
- Clean-Energy Dependence
EVs and wind turbines require high-performance magnets. Magnet insecurity can therefore affect both industrial expansion and energy transition.
- Geopolitical Supply Risk
China’s export controls showed how concentrated supply can expose downstream industries to external policy shocks.
Permanent magnets are therefore strategic supply-chain assets, not merely industrial inputs.
India’s Policy Response
- The National Critical Mineral Mission, approved in 2025, provides a ₹34,300-crore framework covering exploration, mining, processing and recycling.
- India has also approved a ₹7,280-crore Rare Earth Permanent Magnet scheme to establish 6,000 tonnes per annum of integrated manufacturing capacity from rare-earth oxides to finished magnets.
The Missing Gap: Industrial Visibility
- Permanent magnets may enter India directly or embedded inside motors, vehicles, machinery and electronics.
- Conventional trade data may therefore fail to show which sectors are actually dependent on imported magnets.
Integrated Techno-Economic Mapping
ITEM would combine:
Engineering data + Industrial data + Trade data + Economic analysis
It can identify:
- technology bottlenecks;
- vulnerable downstream sectors;
- investment priorities;
- areas requiring international partnerships.
Its value lies in showing where strategic dependence actually exists.
Way Forward
- Build commercial-scale conversion capacity: Focus on metals, alloys and finished magnets.
- Improve value-chain mapping: Track magnets embedded in downstream products.
- Target technology partnerships: Use collaboration to fill specific capability gaps.
FAQs
Q1. Why are NdFeB magnets important?
They offer high magnetic strength in a compact form and are widely used in EVs, wind turbines and advanced machinery.
Q2. What is India’s main weakness?
The major gap lies in converting rare-earth oxides into metals, alloys and finished magnets.
Q3. Why is mineral ownership insufficient?
Because minerals must still be processed and manufactured into usable high-performance components.
Q4. What is ITEM?
A framework combining engineering and economic data to map technological dependencies and bottlenecks.
Q5. What should India prioritise?
Building domestic conversion capability together with better value-chain visibilit
