Even so, global photovoltaic demand for silver has grown at a compound annual rate of 20% over the last decade, according to the Silver Institute''s World Silver Survey 2014. China is now the leader in solarpanel manufacturing, producing 60% of 2013''s global output. Solar capacity in China leapt from to gigawatts between 2010 and 2013, with Beijing setting a target of 70GW by 2017.
Grand Canal, series of waterways in eastern and northern China that link Hangzhou in Zhejiang province with Beijing. Some 1,100 miles (1,800 km) in length, it is the world''s longest manmade waterway, though, strictly speaking, not all of it is a canal. It was built to enable successive Chinese
Rare earth magnets are forecast to form 28% of total demand in 2019, consuming a mixture of rare earths including Nd, Pr, Gd, Dy and Ce. By 2025, rare earth magnets are forecast to exceed a third of total demand, changing the focus of rare earth producers and processors. The changing emphasis towards rare earth magnet raw materials is expected to impact rare earth pricing mechanisms, with ...

To protect the magnet from corrosion and to strengthen the brittle magnet material, the magnet is usually coated with nickel.
The motor that drives these toys is nothing but a permanent magnet DC motor or PMDC motor. These types of motors are simple in construction. They are commonly used as a starter motor in automobiles, windshield wipers, washers, for blowers used in heaters and air conditioners, to raise and lower windows – and they are extensively used in toys. As the magnetic field strength of a permanent ...
