Counter magnets The 1985 Act (§2.c and §8.f) gives the NCRCB the ability to select districts outside of the NCR to act as counter magnets, with a view to developing them further. Counter-magnet cities are identified as those that can be developed as alternative centres of growth and attract migrants to them rather than Delhi. The criteria for selecting counter magnet towns are: that they should have their own established roots and potential of growth, and should not be centres of either religious, strategic or environmental importance. The counter magnet cities should be given priority when allocating funding for development of land, housing and infrastructure. Following are the nine Counter-Magnet Areas to NCR spread across six states: Hisar and Ambala in Haryana Bareilly and Kanpur in Uttar Pradesh Kota and Jaipur in Rajasthan Patiala in Punjab Gwalior in Madhya Pradesh Dehradun in Uttarakhand See also Chennai metropolitan area Kolkata metropolitan area Mumbai Metropolitan Region References External links National Capital Region Planning Board Famous Temples in Delhi NCR NCR map Official area information of districts of India Bulandshahr Official Website Bhiwani Official Site Mahendragarh Official Site National Capital Region (India): Counter-Magnet Areas on Indpaedia National Capital Region Urban Infrastructure Financing
