 How To Make Magnet Charging Machine With Microwave Oven Transformer and DC Capacitor At Home


In the realm of DIY projects, creating a magnet charging machine using a microwave oven transformer and a DC capacitor is a fascinating endeavor. This comprehensive guide will walk you through the process, providing detailed instructions and insights to help you successfully build your own magnet charging machine at home.

In our quest to explore the fascinating world of DIY projects, we delve into the intriguing process of creating a magnet charging machine using a microwave oven transformer and a DC capacitor. This seemingly complex task can be accomplished right in the comfort of your home, with a little bit of patience, some basic understanding of electronics, and a dash of creativity.

The first step in this process involves understanding the components we’re working with. A microwave oven transformer, often abbreviated as MOT, is a high-powered transformer found in microwave ovens. It’s designed to convert low voltage electricity into high voltage, suitable for cooking food. On the other hand, a DC capacitor is an electronic component that stores and releases electrical energy. It’s a crucial part of this project as it helps regulate the flow of electricity, ensuring the magnet charging machine operates smoothly and efficiently.

Now, let’s dive into the actual process of making the magnet charging . Start by carefully removing the microwave oven transformer from an old microwave. Remember, safety is paramount, so ensure you’re wearing protective gear and the microwave is unplugged before you start. Once you’ve successfully extracted the transformer, it’s time to connect it to the DC capacitor. This might sound like a daunting task, but with a little bit of guidance and the right tools, it’s entirely achievable.

To connect the transformer and the capacitor, you’ll need some insulated copper wire. Start by winding the wire around the transformer’s primary coil, leaving enough wire to connect to the capacitor. Then, connect the other end of the wire to the positive terminal of the DC capacitor. The negative terminal of the capacitor should then be connected to the transformer’s secondary coil. This creates a closed circuit, allowing electricity to flow from the transformer, through the capacitor, and back to the transformer.

Once the connections are secure, it’s time to test your magnet charging machine. Connect the transformer to a power source and switch it on. If everything is connected correctly, the machine should start charging the magnet. Remember, this is a high voltage device, so always exercise caution when operating it.

In conclusion, creating a magnet charging machine with a microwave oven transformer and a DC capacitor at home is a rewarding and educational DIY project. It not only provides a practical application of electronics but also offers a great opportunity to learn about the principles of electromagnetism. With the right tools, a bit of patience, and a keen interest in electronics, anyone can undertake this project and successfully create their own magnet charging machine.

Remember, the key to success in this project lies in understanding the components, following the steps carefully, and always prioritizing safety. So, why not give it a try? Dive into the world of DIY electronics and discover the satisfaction of creating your own magnet charging machine.

Understanding the Basics

 What is a Magnet Charging Machine?

A magnet charging machine, also known as a magnetizer, is a device that can increase the magnetic field of a magnet. It works by applying a strong magnetic field to a magnet, thereby enhancing its magnetic properties.

The Role of a Microwave Oven Transformer

A microwave oven transformer (MOT) is a crucial component in this project. It’s a high-voltage transformer that converts the household electricity to the voltage required to power a microwave oven. In our case, it will be used to generate the high voltage needed to charge the magnet.

The Importance of a DC Capacitor

A DC capacitor is another essential component. It stores electrical energy and releases it when needed. In this project, it will be used to store the high voltage generated by the MOT and release it to charge the magnet.

Gathering the Materials

Before you start, ensure you have all the necessary materials. These include a microwave oven transformer, a DC capacitor, a magnet, insulated copper wire, a switch, and safety equipment such as gloves and goggles.

 Building the Magnet Charging Machine

Preparing the Microwave Oven Transformer

The first step is to remove the MOT from an old microwave oven. Be sure to disconnect the microwave from the power source before you start. Once you’ve removed the MOT, you’ll need to remove the secondary coil and replace it with a few turns of thick insulated copper wire.

 Connecting the DC Capacitor

Next, connect the DC capacitor to the MOT. The capacitor should be connected in parallel with the primary coil of the MOT. This will allow it to store the high voltage generated by the MOT.

Adding the Switch and Magnet

The next step is to add a switch to the circuit. This will allow you to control the flow of electricity. Finally, connect the magnet to the circuit. The magnet should be placed in the magnetic field generated by the MOT.

 Safety Precautions


Working with high voltage can be dangerous. Always wear safety equipment and work in a well-ventilated area. Never touch the components while the circuit is powered.

 Testing and Using the Magnet Charging Machine

Once you’ve completed the assembly, it’s time to test your magnet charging machine. Turn on the switch and observe the magnet. If it’s working correctly, the magnet should become significantly stronger.


Building a magnet charging machine with a microwave oven transformer and a DC capacitor is a rewarding DIY project. With careful planning, the right materials, and a focus on safety, you can successfully create a device that enhances the magnetic properties of a magnet.


Can I use any type of magnet for this project?

Yes, you can use any type of magnet. However, the stronger the magnet, the better the results.

What type of DC capacitor should I use?

A high-voltage DC capacitor is recommended for this project. The exact voltage will depend on the specifications of your MOT.

Can I use a transformer from a different appliance?

While it’s possible to use a transformer from a different appliance, a microwave oven transformer is recommended due to its high voltage output.

 Is it safe to handle a microwave oven transformer?

Yes, it’s safe to handle a MOT as long as it’s disconnected from the power source. However, always wear safety equipment when working with high-voltage components.

How can I tell if my magnet charging machine is working?

You can test the strength of your magnet before and after using the magnet charging machine. If the magnet is stronger after charging, your machine is working correctly.
