The Iron Fist is an electromagnetic glove that enables the user to attract light metallic object to their hand.
To attract iron objects we constructed a solenoid with copper wire and an iron core. A magnetic eld is created when this
solenoid is connected to the current. The cylindric metallic core inside the solenoid enhances the eld.
While sticking the solenoid to the palm of the glove, it is possible to direct the eld towards the objects that have to be
To provide current we’ve used 4 lithium batteries, but a power supply could be used as well.
- Fireproof glove
- Metal core
- 4 lithium batteries
- Fishing line
- 2 capacitors
- 2 diodes
- 555 integrated circuit
- Case for the batteries
Step 1: Creating the Solenoid
Wrap the electric wire around the metallic core. We used in total 400 wraps, but the more you have, the
stronger the magnetic eld will be
Remember to not trade quality for quantity, it is recommended to keep the wire well tight while it is
Make sure the solenoid is stable. We used some insulating tape to secure the stability of the structure
Attach the solenoid to the glove using some shing line because it is easy to sew to the glove
Step 2: Create the Circuit
To create the circuit we used the breadboard, the potentiometer, the capacitors, the resistor, the integrated circuit, the
diodes and the cable.
Step 3: Case for the Batteries
We also crafted a case for the batteries to move them easily and to connect them through the wire.
Craft the box. We used some wood, but it’s possible to use other materials
Secure the contacts for the batteries with hot glue
Solder the wires to the intermediate contacts for the chargers’ balancing mechanism
Connect the case to the terminal contacts
