Regularly checking the operating temperature of each critical motor will pay dividends. It is no secret that heat kills electric motors. But it is easy to forget that exceeding the rated operating temperature by as little as 10 C 18 F can shorten the life of a threephase induction motor by half. The first step

Hello friends last time we have discussed about electric flux and its units. Similarly in magnetism there is concept of magnetic flux. Have you imagined why a magnet able to attract an iron piece place near by it but if the iron piece is placed somewhat far away from magnet then magnet is not able to attract it.
