# How does a simple Homopolar motor work?

Contents

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 is a homopolar motor simple explanation?

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.

## What happens in a homopolar motor?

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.

## 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 magnetic motor work?

This simple electric motor works by the magnetic force F = IL x B. The magnetic field at both of these spots points in the same direction. … Thus, the magnetic force on the wire at opposite ends of the loop points in opposite directions, causing it to spin.

## 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.

## What is the use of homopolar motor?

Homopolar motors have been used in high-torque wind turbines. The mechanics of the motors provide a low-cost means of converting wind into electricity because of the reduced need for multidirectional gears. These motors also require less maintenance than bipolar motors.

## How do you make Homopolar?

## What does Homopolar mean?

1 of a motor or generator : using or producing direct current without the use of commutators. 2 : of or relating to a union of atoms of like polarity : nonionic.

## How does Faraday’s homopolar generator work?

The first homopolar generator was developed by Michael Faraday during his experiments in 1831. … Later homopolar generators would solve this problem by using an array of magnets arranged around the disc perimeter to maintain a steady field around the circumference, and eliminate areas where counterflow could occur.

## What happens when you wrap copper wire around a magnet?

By simply wrapping wire that has an electrical current running through it around a nail, you can make an electromagnet. When the electric current moves through a wire, it makes a magnetic field. If you coil the wire around and around, it will make the magnetic force stronger, but it will still be pretty weak.

## Is it bad to put a magnet on a battery?

Re: Magnets and Batteries

Attached is a page from an FAQ put out by Energizer, the battery manufacturer, that also states that magnetic fields have no effect on battery performance.

## How can you create a strong electromagnet?

You can make an electromagnet stronger by doing these things:

1. wrapping the coil around a piece of iron (such as an iron nail)
2. adding more turns to the coil.
3. increasing the current flowing through the coil.
