Things to Consider While Designing Electromagnets for Sale

By James Blee Subscribe to RSS | April 23rd 2012 | Views:

Electromagnets are a specially designed metallic core with coils of copper wire wrapped around its body that forms a magnetic field on passing electricity through its surface. These find widespread applications in a large number of devices of both residential and commercial usage. This is what makes the electromagnets for sale very high in demand.

However, when it comes to constructing electromagnets, certain factors needs to be taken into consideration. First and foremost, give additional focus on the materials that are to be used. Coming to the materials, the metallic cores and the wires are the two most vital things that demand a fair amount of pondering. Generally, iron is used to design the cores. Next, talking of the coils, the number of turns and material to be used is primarily dependent on the strength of the electromagnet that is being made.

Ensuring proper insulation of the electric wires is another most vital thing to consider. The insulator must be able to withstand the current strength flowing through it. Along with this, consider the technical aspects associated with the process as well. The flux density, on the other hand is determined based on the number of turns. Similarly, the number of turns is directly proportional to the magnetic field. Therefore, the number of turns should be calculated and decided upon with care.

Finally, the supply voltage should be controlled to get the maximum benefits. Remember that over voltage commonly leads to melting of the cores which in turn is going to dampen the function ability of the electromagnets. On the other hand, a too smaller voltage is going to reduce the electromagnetic properties. Therefore, proper calibration of voltages is a necessity. NiCad batteries are prone to explosions and therefore alkaline batteries should be preferred over the former varieties.
