## Introduction: How to Make an Electric Motor

When a current is passed through the wire, a magnetic field is generated around it. This principle is the basis of building electromagnets, motors and much more.

In this Instructable, i decided to demonstrate this principle by performing a simple Experiment of making an Electric Motor at home. An electric motor can be simply made using enamel wire, magnets and battery.

Note: This motor is fairly weak, and won't generate enough power to move anything. However, it is a good learning experience and will make a great science fair project.

## Step 1: Watch the Video

A video is a wonderful tool that provides clarity to the procedure and makes it easy to follow. However, also visit next steps for additional details and images.

## Step 3: Prepare Wire Loop

1. Take a thick enameled copper wire (i used 28 AWG wire).
2. Leave few inches of wire and wrap it around an AA battery to form circular loops.
3. Make around 12-15 loops and then cut the wire.
4. Remove the battery carefully.
5. Wrap both the loose ends of the wire on the loop at the opposite sides to form a coil as shown in the image above.
6. Using stationary knife, carefully remove the enamel coating from the wire ends.
7. Make sure to only remove half of the coating from the wire.
Note: Refer to the images to avoid any errors.

## Step 4: Make Coil Holder

1. Take two office paper clips.
2. Using Pliers, fold the clips in such a way that there is hole at the center of the clip as can be seen in the images above.
3. Take a 1.5v high current battery.
4. Using neodymium magnets, sandwich the clips to both the battery terminals.
5. Place a strong magnet at the center of the battery.
6. The holes in the clips will be used to hold the coil.

## Step 5: Principle of Operation

When the loop sits on the metal conductor (i.e paper clips), the current flows through it, thus producing a magnetic field around the coil. When the loop rolls over, there will be no contact due to half enamel coating and thus, no current flow and no magnetic field. When another magnet is placed to interact with the coil, the coil spins continuously because the magnetic field around it tries to align with the magnetic field of the permanent magnet.

## Step 6: Testing the Motor

Our Homemade Electric motor is now ready. Insert the coil in the paper clips and give it a slight push. The coil will spin continuously till any external force is applied to stop it or if the battery dies.

Note: If the coil gets too hot, try using a thicker wire or reduce the amount of power to the coil.
