Arc magnets can be made from powerful neodymium. They are often used in electric motors, alternators and generators or to create renewable energy from wind, solar and hydro power sources. Stators and Rotors inside electric motors use permanent magnets in the shape of an arc.

In 2003, iron ore began to increase in price, attracting social capital to invest in metallurgical mines. In 2004 and 2005, metallurgical mine construction investment grew rapidly, and its momentum was no less than that of the steel industry at that time. According to statistics, in 2003, the national metallurgical mine investment was about 5 billion yuan; in 2004, the investment was more than 13 billion yuan, a year-on-year increase of 165%;
In 2005, the estimated investment is 25 billion yuan, a year-on-year increase of 90%, which is five times the amount invested in 2003.
There are few open-pit mines with large mining conditions in China. In recent years, most of the metallurgical mines invested and constructed are underground mines. It takes more than three years for the underground metallurgical mine to go from investment to production. That is to say, the mines invested in 2003 will form capacity at the end of 2006, and a large number of mines invested in 2004 and 2005 will release capacity in 2007 and 2008.
At the same time, the three major international iron ore suppliers plan to increase production of 200 million tons of iron ore by 2008. From the perspective of domestic small and medium-sized mining enterprises, due to the high price of iron ore and increased profit margins, the cut-off grade of iron ore development has dropped from the previous 25% to 17%, and even 13% of mines have been exploited. Considering various factors at home and abroad, the inflection point of the domestic iron ore supply situation may appear at the end of 2006.
Industry experts pointed out: the rule of gold mining companies to be alert to production release impact on the market situation, to plan for it in advance. In the current domestic iron ore as well as half of "foreign aid" situation, this view is unfounded? According to industry experts, the investment in domestic metallurgical mines is concentrated from 2003 to 2005. According to the production cycle, production capacity will be released from the end of 2006, which will inevitably affect the domestic iron ore supply situation.
