Quick Answer: How To Build A Homopolar Motor?

How does a homopolar motor work?

A homopolar motor is one of the simplest motors built due to the fact that it uses direct current to power the motor in one direction. The magnet’s magnetic field pushes up towards the battery and the current that flows from the battery travels perpendicularly from the magnetic field.

What type of magnet Do you need to make a homopolar motor?

How To Make a Simple Homopolar Motor? To make Homopolar Motor you’ll need wire, a battery, and neodymium magnets.

How do you make a homopolar motor without copper wire?

A neodymium magnet is a rare-earth magnet made of neodymium and is extremely strong. Apply your magnet carefully to the bottom of the battery. Place the battery/magnet assembly on a flat surface. Bend your wire into a heart shape.

How do you make a motor for a science project?

Procedure

  1. Starting in the center of the wire, wrap the wire tightly and neatly around the marker 30 times.
  2. Slide the coil you made off of the marker.
  3. Wrap each loose end of the wire around the coil a few times to hold it together, then point the wires away from the loop, as shown:

Why does my Homopolar Motor not work?

If the motor doesn’t begin to spin, try flipping the magnet so the other side is touching the battery. If it still doesn’t work you will need to tweak your wire sculpture. Remove the battery from the magnet while you work, so it does not get too hot.

Why does copper wire spin on a battery?

What happens: The copper wire will spin around. When the wire touches the top of the battery and the magnet, it is making a circuit, which allows electrons to flow – this is the current. This force, which is called a Lorentz Force, acts on the wire and causes it to move, which makes the wire spin around.

How does a simple electric motor work?

This simple electric motor works by the magnetic force F = IL x B. The current goes around the coil so that it points one direction in one end of the loop and in the other direction at the other end of the loop. The magnetic field at both of these spots points in the same direction.

How do you make an electric motor with a battery magnet and a copper wire?

Gently place the free end of the copper wire to the side of the magnet. The magnet and the screw should start to spin. When you place the copper wire to the side of the magnet, you complete the circuit between the battery terminals. The current flows from one end of the battery, down the screw, and into the magnet.
