Iron Fist
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 field is created when this solenoid is connected to the current. The cylindric metallic core inside the solenoid enhances the field.
While sticking the solenoid to the palm of the glove, it is possible to direct the field towards the objects that have to be picked up.
To provide current we've used 4 lithium batteries, but a power supply could be used as well.
Supplies
- Fireproof glove
- Cables
- Metal core
- 4 lithium batteries
- Fishing line
- Switch
- Potentiometer
- Breadboard
- 2 capacitors
- 2 diodes
- Resistor
- 555 integrated circuit
- Case for the batteries
- Wires
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 field will be
- Remember to not trade quality for quantity, it is recommended to keep the wire well tight while it is wrapped
- 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 fishing line because it is easy to sew to the glove
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.
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
