Experimenting with Magnetic Components: About the Competition

Experimenting with Magnetic Components

About the Competition

As far back as 1820, when Hans Christian Ørsted  passed a current through a wire causing a compass need to move due to the magnetic field produced (Ørsted’s Law),  magnetism has inspired simple experiments that would ultimately change the world with a slew of innovations. Michael Faraday's simple experiment of passing a magnet through a cardboard tube wrapped with wire causing an induced EMF (Faraday’s Law of Induction) formed the foundation of commonplace devices like the electric motor, transformer, generator, and electric guitar pick up.

 

Today's generation of magnetics are finely engineered devices that are utilized in advanced applications, spanning power conversion, filters, oscillators, circuit isolation, and many more. To this end, element14's Experimenting with Magnetic Components competition is an opportunity to provide our participants a kit of magnetic components so they can conduct their own experiments and blog about what they learned. Our judges will select the best experiment-blog reports and award some really great prizes to the winners.

What kind of experiments can the participants perform?

It depends on your interests! EMI suppression, filters, DC/DC converters, power line noise suppression, isolation power supplies, and more. It's totally up to you, so use your imagination and creativity.

 

What do I need to do to win the Grand Prize or Runner Up Prize?

After the month long enrollment period is complete, and the 10 FREE magnetic component kits are shipped, you will have 8 weeks to complete your experiments, write two blogs, and share what you learned about magnetic components. You will be judged by the quality of your final blog and what you learned about these components.

 

What do I get if I don't win the Grand Prize, but I wrote the two blogs?

If you successfully finish, yet are not the grand or runner-up prize winners, you will be eligible to receive the finisher prize. But remember, you have to write two blogs by the deadline to be considered a finisher!

JOIN THE CHALLENGE

Who is Eligible to Enroll?

Any element14 member can enroll in the Experimenting with Magnetic Components competition. But to receive one of 10 FREE magnetic component kits, you need to submit an application by the enrollment deadline, September 10th, 2021. (If you're not an element14 member go to https://www.element14.com/community/create-account.jspa to create an account or register here. It takes less than a minute to register.)

Tips on Writing Your Application

If you want to get a chance to obtain one of the 10 FREE Kits, you will need to submit an application no later than September 10th, 2021. The key to a winning application is to provide as much meaningful information about your proposed experiments as possible.

Please don't write a book! The application should be detailed enough to give the judges a good idea of what you plan to do and how you plan to pull it off. By answering each of the following questions in your application, you will provide the judges with the information they need to make their decisions:

(a) Describe your technical background.

(b) Why are you interested in this competition? What's your interest or experience with magnetic components?

(c) What kind of experiment(s) do you plan to perform? (Be as specific as you can)

(d) Have you participated in the element14 Community? If so, please provide some links to what you've done. If you are a new member, answer "New Member."

All interested element14 members must submit an application before the end of enrollment on September 3rd, 2021.

Here are some other suggestions for completing a winning application:

1. Please complete all required information (contact information, etc.)
In the Project Title field,  use "Experimenting with Magnetic Components" or your element14 member name.  Please use the email address that is associated with your element14 profile.

2. Complete all of the application questions
Tell us why you want to be selected. Before deciding what you want to write, think about the following things:

  • You are entering a competition. The most persuasive applications are the ones that attract the eye of the judges.
  • A single sentence application will never be selected. This competition is not a game of chance.
  • Be as detailed as possible, but don't write a book.

 

Anyone Can Participate in Experimenting with Magnetic Components

Any element14 member can enroll in the 'Experimenting with Magnetic Components' competition. To receive one of the 10 FREE magnetic components kits, you need to submit an application by the deadline, September 10th, 2021.

    Jan,

     

    This does require the use of an LCR meter, which I do not have. I'm not sure if I regret this or not as I have never used one in my entire life so far. I'm not even sure that where I was studying for my degree had any either.

    It doesn't require a meter. I only have an LCR since one year, I've gotten by without one for the other 53 years of my life.. And the inductors in the kit are specified.

    There are also a few methods to measure inductance without LCR meter. I've tested one of them: Measure Unknown Inductor Value with Function Generator and Oscilloscope

    I have an LCR meter, mostly exclusively for checking capacitors. I dont have a newer Fluke DVM that can check cap values.

     

    Whenever I need chokes to solve noise problems, I'm always looking for snap on ferrite cores.

    It works - or at least it oscillates. I've not done the calculations yet.:

    DD, I've made a DIY Inductance Meter for the design challenge.

    You need a frequency counter (or oscilloscope, or DMM with Freq capability).

    I think an arduino can be used as a frequency counter for this project. Easy to interface with LCD/OLED also.

    Yes, up to 1 MHz I believe.

    You'd need to attenuate (or maybe better, clip into a block wave)  the signal or the Arduino gets damaged.

    With a 13 V supply and a 47 µH inductor, it bounces between -1.56 and +4.58 V.
