Introduction: (Initial Observation)

An electromagnet is a key component of many household and also industrial equipments. Electrical bell, speaker, television, relay, electric valve, computer hard drive and thousands of various other machines can not exist without electromagnets.

You are watching: How does the number of coils affect the strength of an electromagnet

Because that the prominence of the electromagnet and its substantial use in different machinery, it has been a difficulty for scientists to make stronger electromagnets without raising its size and without using much more material. For example, an electric valve supplied in a dish washing an equipment is utilizing an electromagnet come open and close the valve. If the electromagnet is not solid enough, the valve might fail to open or may fail to close when needed.

In this project you will examine the factors affecting the strength of an electromagnet.

The result of this project deserve to be provided in making stronger electromagnets.

Information Gathering:

Gather information about electromagnets. Read books, magazines or ask experts who might know in order to learn about the components that may impact the strength of one electromagnet. Save track of where you got your info from.

Following space sample of information that you might find around electromagnet.

An electromagnet is simply a coil the wire. That is commonly wound approximately an iron core. When connected to a DC voltage or a present source, the electromagnet i do not care energized, developing a magnetic field just like a long-term magnet.

Electromagnetism II

In her studies around electromagnetism, you have actually learned around the electromagnetic field formed about a single conductor. A different problem exists once two parallel conductors room carrying equal currents in the very same direction. A magnetic field forms in the clockwise direction approximately each conductor, through the magnetic lines in between the conductors opposing every other. The magnetic field in between the conductor is canceled out, leaving basically no ar in this area. The 2 conductors then relocate toward every other, from a strong field into a weak field.Two conductors lying together each various other carrying equal currents in the same direction produce a magnetic ar equivalent come one conductor carrying twice the current. When several much more conductors are placed side through side, the magnetic effect is enhanced as the present from each conductor join and also surround all the conductors.
