ELECTROMAGNET

Electromagnet in a type of magnet whose magnetic field is produced by the flow of current through it.



In this picture you can create a magnet by wrapping a wire in a steel or plastic tube and connecting the wire to a supply or battery.

There are three ways to make electromagnet more stronger:
a. By winding more wires around the tube
b. Increasing the flow of current in the wires
c. And by putting a soft iron inside the tube

Putting soft iron inside the tube creates more concentration of magnetic fields inside the tube and increases the magnetism.



There's a lot of things where you can see electromagnets like in generators, hospitals (MRI Scanner) , Factories etc.

Magnetic flux lines

Magnetic flux is used to describe as the total amount of magnetic field in a region
The term flux was chosen because the power of a magnet seems to "flow" out of the magnet at one pole and return at the other pole in a circulating pattern, as suggested by the patterns formed by iron filings sprinkled on a paper placed over a magnet or a conductor carrying an electric current. These patterns are called lines of induction.
Although there is no actual physical flow, the lines of induction suggest the correct mathematical description of magnetism in terms of a field of force. The lines of induction originate on the north pole of the magnet and end on the south pole; their direction at any point is the direction of the magnetic field, and their density (the number of lines passing through a unit area) gives the strength of the field. Near the poles where the lines converge, the field and the force it produces are large; away from the poles where the lines diverge, the field and force are progressively weaker

Circuit Maker Practice

I tried to use Circuit Maker program and it is easy, fast, and

helps me a lot. I tried to draw one of our exercises in this program

and it takes me a only a few minutes. However I still finding some

trouble in converting a Schematic drawing to Vero board layout.

If you want to send me some links to help me converting it just comment

the links...thnx

Solving a Circuit

This is an example of a Series-Parallel circuit.

How I solve it?

1. I always check the circuit first, if it is a Series, Parallel, or Series-Parallel Circuit.
2. Then I'll find the formula for the specific circuit and write down what is missing in the circuit.
3. The total voltage, resistance for each resistor, or the current is always given in the circuit. You will usually need to find the voltage passing through the circuit, total resistance, total current, current passing through each resistor, and Power
4. Remember that different circuit has always different formula and the Series-Parallel is a combination of the two circuit.

Here's a link for the formula about the circuits.

Spreadsheets

Here's my spreadsheet about E12 Range for Series and Parallel.

I hope it helps.

Thnx,

Dan

Series and Parallel Circuits

Series Circuits

-A circuit composed solely of components connected in one continues path
-The total voltage is the sum of the volt drops
-And the current are the same at every point





Parallel Circuits

- If two or more components are connected in parallel their voltage is the same
across every branch and the total current is the sum of branch current

Resitor Color Code

This is a one example of a resistor.... It is a 5-Band-code
Do you know how to read it to find out what's the minimum and maximum resistance??

This is how I do it...

First I will found the tolerance band...that is the last band after the
big gap...in the picture above the color of the tolerance band is a gold.. that is plus and minus 5%

Then I look up the color code table



Then I always read it backwards....I start with the multiplier and put all the zero then the rest of the bands...

In the resistor above the multiplier is black...the multiplier is always tells you how many zero's you have in the band..... black has no zero's and don't
have to put it... then

White = 9
Orange= 3
Orange= 3

933 is the reading up to the fourth band then plus and minus it to 5% to get the minimum and maximum resistance...

5% of 933 is...46.65

Minimum: 933-46.65 = 886.35 ohms

Maximum: 933+46.65= 979.65 ohms

I hope this thing helps you...


Thnx,

Dan

Computer Ergonomics

What is Ergonomics??

Ergonomics is derived from two Greek words: “ergon”, meaning work and “nomoi”, meaning natural laws. Ergonomists study human capabilities in relationship to work demands.

Ergonomics: is also the science of designing the job, equipment, and workplace to fit the worker.
Survey says that ergonomics can reduce work-related illness, high staff turnover, muscle fatigue , visual fatigue by 40 percent and improves company productivity as well. Ergonomists redesign the environment,workstation in the workplace to suit each employee.

These are some of the benefits of the new design

-lower injury and accident rates
- improved reliability
- products that are easier to use
- systems and products that operate efficiently
- greater user comfort
- faster learning times
- fewer errors
- easier maintenance
- improved aesthetics
- a general increase in job satisfaction
- less absenteeism
- less labour turnover (with less recruitment, training time, down-time costs).
- improved competitiveness of products and services
- increases in productivity.

Generating Scheme - Nuclear Power

Nuclear Power seems to be every country's or many politicians have in mind.

WHY??

• Nuclear Power emits very low amounts of Carbon Dioxide (CO2)
• This technology is readily available, it does not have to be developed first.
• It's possible to generate a huge amount of electricity in one single plant

However,,...

• Nuclear Power Plants has a radioactive waste that are harmful to the people and the dispossal of the waste is still unsolved.
• It is expensive to build and takes a lot of time to be built
• It uses Uranium, and its supply is estimated to last only for the next 30 to 60 years depending on the actual demand.

Hello! This is dan! This is what we did today we tested the potato if it has an electricity and the answer is yes. We stick one copper nail and one steel nail inside the potato with the heads up. Then we get a digital multimeter to measure how many millivolts it has. If you want to know more click on this one and try it yourself as well.

Thnx!

New Post

Hi this is Dan Baterina and this is my first blog.

This is the my 4th week here at Unitec and I'm studying Electrical and Electronics Engineering. I have learned lots of things in our theory class in the past few weeks like solving triangles, force,vortex,conversions and a lot more, which can help me in the future.
We also did an 4 exercises in hand skills, on what tools we need to use and how to use it, we drill different diameter of holes in a piece of 10mm steel and also in a thin plate and put the together.
I also leaned how to solder and it is hard at first but once you get use to it, it is easy.

I will post some pictures in my next blog and thank you for reading my blog.
