Introduction to Electric Magnetic Suspension Toys
Electric magnetic suspension toys, also known as electromagnetic suspension (EMS) toys, are fascinating gadgets that use the power of magnetism to suspend objects in mid-air. These toys are not only entertaining but also educational, as they demonstrate the fundamental principles of electromagnetic forces. In this article, we will explore five ways to build electric magnetic suspension toys, highlighting the materials, techniques, and safety precautions involved.
Method 1: Basic Electromagnetic Suspension using a DC Motor
This method uses a DC motor, a magnet, and a battery to create a simple electromagnetic suspension system.
Materials:
- DC motor
- Magnet
- Battery (9V or 12V)
- Wire
- Switch
- Small metal object (e.g., a paperclip)
Step-by-Step Instructions:
- Connect the DC motor to the battery using the wire and switch.
- Place the magnet near the motor, making sure it is aligned with the motor’s axis.
- Suspend the small metal object (e.g., paperclip) above the magnet using a thread or string.
- Turn on the motor, and adjust the distance between the magnet and the metal object until it is suspended in mid-air.
Note:
[⚠️] Note: Be careful when handling the magnet and metal object, as they can cause injury or damage if not handled properly.
Method 2: DIY Electromagnetic Levitation (Maglev) Train
This method uses a more advanced approach to create a Maglev train that can levitate and move along a track.
Materials:
- Copper wire
- Wooden or plastic track
- Neodymium magnets
- Battery (9V or 12V)
- Switch
- Small object (e.g., a coin)
Step-by-Step Instructions:
- Create a track using the wooden or plastic material, with a width of about 1 inch (2.5 cm).
- Wrap the copper wire around the track to create a coil.
- Place the neodymium magnets along the track, spaced evenly apart.
- Suspend the small object (e.g., coin) above the magnets using a thread or string.
- Connect the coil to the battery using the switch.
- Turn on the power, and adjust the distance between the magnets and the object until it is suspended and moving along the track.

Method 3: Using an Arduino Board and LED Lights
This method uses an Arduino board and LED lights to create a more sophisticated electromagnetic suspension system.
Materials:
- Arduino board
- LED lights
- Neodymium magnets
- Battery (9V or 12V)
- Switch
- Small object (e.g., a paperclip)
Step-by-Step Instructions:
- Connect the LED lights to the Arduino board and write a program to control the lights.
- Place the neodymium magnets near the LED lights, making sure they are aligned with the light’s axis.
- Suspend the small object (e.g., paperclip) above the magnets using a thread or string.
- Turn on the Arduino board, and adjust the distance between the magnets and the object until it is suspended in mid-air.

Method 4: Creating a Homemade Lenz's Law Coil
This method uses a coil and a magnet to demonstrate Lenz’s Law, which states that an induced current will flow in a direction that opposes the change in magnetic flux.
Materials:
- Copper wire
- Cardboard or plastic tube
- Neodymium magnet
- Battery (9V or 12V)
- Switch
Step-by-Step Instructions:
- Wrap the copper wire around the cardboard or plastic tube to create a coil.
- Place the neodymium magnet near the coil, making sure it is aligned with the coil’s axis.
- Connect the coil to the battery using the switch.
- Turn on the power, and observe how the magnet is repelled or attracted to the coil.
Note:
[🔧] Note: This method demonstrates a fundamental principle of electromagnetism and can be used to create more complex electromagnetic suspension systems.
Method 5: Building an Electromagnetic Suspension using a Hall Effect Sensor
This method uses a Hall Effect sensor to detect the magnetic field and create a more stable electromagnetic suspension system.
Materials:
- Hall Effect sensor
- Neodymium magnets
- Battery (9V or 12V)
- Switch
- Small object (e.g., a paperclip)
Step-by-Step Instructions:
- Connect the Hall Effect sensor to the battery using the switch.
- Place the neodymium magnets near the sensor, making sure they are aligned with the sensor’s axis.
- Suspend the small object (e.g., paperclip) above the magnets using a thread or string.
- Turn on the power, and adjust the distance between the magnets and the object until it is suspended in mid-air.
Note:
[🔮] Note: This method requires knowledge of electronics and programming. Ensure proper safety precautions when working with electricity and magnets.
