How to measure inductance?

Hi meenal,

Normally the value of inductors can be measured using LCR meters. There are some multimeters which could do that task but they are mosly not accurate.

In your case the simplest thing that you can do it use a formulae to calculate the inductance value of your inductor. The formulae is shown below

This formulae is applicable only for air-cored single layer inductor. Do keep in mind that the obtained value will only be close to practical value 

Jayant has already suggested the simplest way. However if you are onto measuring inductance values for your future projects also then it is better to build a LC meter by yourself. A crude one can be easily built using Arduino and Op-Amp the circuit diagram for the same is given below

The code and other details for this meter can be found here: https://circuitdigest.com/microcontroller-projects/arduino-lc-meter-mea…

Again these readings are only to give you an rough estimate and are not highly reliable.

Multiply these amounts and divide the product by the peak current. This is the amount of inductance of the device being tested. Another method for measuring inductance using an oscilloscope involves connecting a resistor of known value in series with the inductor under test and applying a signal.

Inductance is usually measured in units called millihenrys or microhenrys. It is commonly measured by using a frequency generator and an oscilloscope or an LCM multimeter. It can also be calculated through a voltage-current slope measuring the change in the electrical current passing through the coil.

Few things in addition.
You are making a aircore coil. It is extremely difficult to make because even simple change in the turning or space between each turn will drastically drift the inductance value. However, such microhenry measurements are also critical in any measurements tool because of the added inductance of the probes.

I will suggest you to use dedicated lcr meter for this. Otherwise try to used a wide range of capacitive trimmer possible from 5pF to 250pF amd tune the circuit. It will be easier for you.

Always use proper pcb.
