Magnetic circuits and transformer

AI Thread Summary
A UG electrical engineering student seeks practical project ideas related to magnetic circuits and transformers. Suggestions include building simple 1:1 communication transformers and exploring audio projects, with resources available through local stores or online distributors like Digikey and Mouser. The student, located in India, notes limited local availability of materials and expresses intent to research distributors. There is a suggestion to find an Indian equivalent of Digikey to facilitate ordering necessary components. Engaging in these projects can enhance understanding of the concepts studied in class.

I am a UG electrical engineering student. I studied about magnetic circuits and transformers recently in one of my departmental courses.

I want to find out if I can implement this knowledge practically. So can anybody suggest some interesting projects on magnetic circuits or transformers which can give me an opportunity to implement the concepts I studied?

Where are you located physically? Do you have stores near you that carry magnetic materials for making transformers? Here in Silicon Valley, there are a number of hobby and regular stores with bobbins and various cores.

Alternately, do you have access to ordering from companies like Digikey and Mouser? You should be able to order some bobbins and cores from them, and some magnet wire of whatever size you choose for your projects. It helps to have an actual bobbin winder (even a simple hand-crank one), but in a pinch, if you're patient and careful, you can wind pretty good bobbins.

You can start out building simple 1:1 communication transformers, and test them with a signal generator and oscilloscope. You can then play with some audio projects -- do a google search, and you will find many autio projects that involve transformers.

Have fun!

Thanks berkeman our for your reply. I live in India. So there are not many stores of this kind around me. But I'll have to search.
I'll google for audio transformer. It might be helpful.

There must be an Indian equivalent of Digikey. India seems like a pretty high-tech country. Are you able to order from US distributors like Digikey, or do you have to order from Indian distributors? The key for projects like these is to find a distributor with reasonable minimum order quantities and minimum order total cost.

Sorry but I don't have any idea. This is the first time I want to work on a project. So I'll have to make some research about distributors.

I googled digikey india, and got a lot of hits. Please check out the hit list in case it helps:

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...
suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
