1. Introduction
The motor is an electrical device, which converts electrical energy into the mechanical energy. The electric motor operates by the interaction of the magnetic and the current to generate the force. The electric motor operates in generating or braking modes. The industrial fans, pumps, and motors are being powered by the direct electric current sources. The small types of motor is being found in the electric watches [1]. The motor has highly standardized dimensions with the good mechanical power to the industries. The high capacity motors is being found in the ship propulsion and compression. The ...

Magnetism is the ability of a material to exhibit attraction or repulsion of certain magnetic materials due to the presence of magnetic fields. Magnetism may be permanent or temporary depending on whether a material is a hard or soft magnetic material. Magnetism arises from the existence of small atom-like structures referred to as magnetic domains that, when aligned, cause the effect of magnetism to be pronounced in a magnetic material (Huebener, 135).
Magnetism depends on the alignment of domains and in the same direction. As such, increase in temperatures results in increased random movement of domains, and hence affecting their alignment. On ...
