Let's say I want to create an eletromagnetic field with a 13.56Mhz frequency... How do I proceed it with a circuit? I don't need a large explanation, but please tell me how do I learn about it. Thanks :)

mitocondrio said:I want to do some RFID emulation, but I would like to learn how to create this frequency. I already learned the modulation part. I want to learn by parts. I will thank you so much if you can help me!
mitocondrio said:I'm studying RFIDs and how they work. I would try to do an RFID emulator just to learn better how things work. It's nothing under the government specifications, I will just use this to emulate an RFID tag for like 10 centimeters away form the reader. The tags I want to emulate uses the 13.56Mhz frequency, which is the frequency I wanted to create with a coil.
Thanks!

To create an electromagnetic field with a specific frequency, you will need a power source, a conducting wire, and a source of AC current. You can use an oscillator or a generator to create the desired frequency. The wire should be wrapped into a coil, and the AC current should be passed through it. This will create an electromagnetic field with the desired frequency.
Yes, you can control the strength of the electromagnetic field by adjusting the voltage and current of the AC source. Higher voltages and currents will result in a stronger electromagnetic field, while lower values will result in a weaker field.
The most commonly used material to create an electromagnetic field is copper wire, as it is highly conductive. However, you can also use other conductive materials such as aluminum or gold. The key is to have a material that allows for the flow of electricity.
The range of an electromagnetic field depends on the strength of the field and the materials it encounters. In most cases, the field will dissipate quickly as it encounters resistance in the form of air or other objects. However, in certain conditions, such as in a vacuum, the field can travel very far.
There are many practical applications of creating an electromagnetic field with a specific frequency. These include wireless communication, medical imaging, industrial processes, and research in various fields such as physics and biology. The ability to control the frequency of the field allows for precise and targeted use in these applications.
