Motor Listrik Sederhana - Gaya Lorentz
Summary
TLDRIn this engaging video tutorial, the host demonstrates how to create a simple electric motor using the principles of Lorentz force. The project involves essential materials such as copper wire, a plastic cup, magnets, and a battery. Step-by-step, viewers learn to wind copper wire into a coil, prepare the plastic cup, and assemble the components. The interaction between electric current in the copper wire and the magnetic field generates the Lorentz force, allowing the coil to rotate. This hands-on experiment illustrates fundamental physics concepts in a fun and accessible way.
Takeaways
- 🔌 The project involves creating a simple electric motor based on the Lorentz force principle.
- 🛠️ Required materials include copper wire, vacuum plastic cups, magnets, batteries, scissors, sandpaper, and Styrofoam.
- 🔄 The first step is to wrap the copper wire around a cylindrical object, creating 10 loops while leaving 3 cm of wire at both ends.
- ✂️ Carefully remove the coil and secure it using tape.
- 🧰 Drill holes in the plastic cup with a heated nail, placing two holes at the top and two at the bottom.
- 📏 Use two pieces of 20 cm long wire and insert them into the plastic cup as demonstrated.
- ⚡ Strip the insulation off both ends of the wires to prepare them for connection.
- 🌀 Shape the wires to support the copper coil effectively.
- 🧹 Sand the ends of the wires and the copper coil to ensure good electrical contact.
- 🔄 The interaction between electric current in the copper wire and the magnetic field produces a magnetic force, resulting in torque that causes the coil to rotate.
