How do you increase the speed of a homopolar motor?

Hints for Improving the Performance of Homopolar Motors: Always use magnets that are slightly larger than the diameter of the battery. If they’re smaller, it can be hard to get the bottom of the armature to slide down the larger battery. If they are very much larger, they limit the shape of some armature designs.

How do you make a homopolar motor step by step?

Easy DIY Homopolar Motor

  1. Step 1: Gather Your Materials. For this instructable you need-

What are features of homopolar motor?

A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field.

Are homopolar motors efficient?

Regardless of the design changes, the homopolar motor analyzed here is capable of operating at no more than 50% efficiency.

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.

Do you need copper wire for a homopolar motor?

Before you can start making a homopolar motor you need a double A battery, Copper wire (The thicker the wire, the slower the motor will go), Neodymium magnet (also known as “rare earth magnets”), Needle nose pliers, and a Wire cutter.

What kind of wire does a homopolar motor use?

Make sure your wire is copper, and doesn’t have insulation or a plastic coating. Thick wire (14-16 gauge) works best. Measure 6” of wire using the ruler, then cut it using the wire cutter. 2.

What happens if you put a battery on a magnet?

No, a magnet will not affect a common household battery. Only in the case of a science lab and high-powered magnets will electronic devices be affected.

What is a homopolar motor used for?

A homopolar motor creates rotational movement because of what is known as the Lorentz force. What’s happening is that electrical current is flowing from the positive terminal of the battery to the negative and into the magnet.

What are the components of a homopolar motor?

This homopolar motor provides a compact way to demonstrate the effects of the Lorentz force acting on moving charges in a magnetic field. Homopolar motor bin: Located in cabinet F3. The contents include an AA battery, cylindrical magnet, nut, metallic stand, and two molded copper wires. These components are shown below in Figure 2 and Figure 3.

When was the first homopolar motor made?

It was the first type ever built and demonstrated by Michael Faraday in 1821. Although not the configuration Faraday used, homopolar motors can be made out of a single AA or C battery, a single neodymium disc magnet and a piece of copper wire.

What is a homopolar motor bin?

This homopolar motor provides a compact way to demonstrate the effects of the Lorentz force acting on moving charges in a magnetic field. Homopolar motor bin: Located in cabinet F3. The contents include an AA battery, cylindrical magnet, nut, metallic stand, and two molded copper wires.

How do you spin a homopolar motor?

Now insert the battery through the top of the spiral winding. And finally, place the pointed end of the spiral winding onto the positive terminal of the battery to watch it spin. The homopolar motor spins by turning the electrical energy stored in the battery into kinetic energy by the Lorentz force.
