Instructions

STEP 1
0:00

Reach into your kit & pull out the bag that says Experiment 24. Take everything out of the bag and place it around your white mat.

STEP 2
0:29

Place the orange card with the rectangle on the center of your mat. Then grab a piece of copper wire.

STEP 3
1:33

First, bend the piece of wire in half. Use the pliers to squeeze the center together to make a point.

STEP 4
2:06

Using your card as a guide, slowly bend the wire into the same shape. You can check your bends as you go.

STEP 5
3:56

Next, Place the battery in-between the two ends of the wire and bend them around the battery. The wires should lightly hug the battery.

STEP 6
4:54

Grab one of the rubber connectors, with the metal side up, push down and turn it with the onto the plus side of the battery.

STEP 7
5:58

Next, take out your magnet and connect it to the negative side of your battery. It should stick.

STEP 8
6:14

Now using the bends you made in the wire, place it over the battery and slide it down to hug the magnet below the battery, and it should start to spin. You can play with loosening the wires around the battery to make it spin faster.

STEP 9
10:09

Next, let’s try another shape. Grab the card with the heart shape and place it on the center of your mat. Just like before, bend a new piece of wire in half using your pliers and then work the shape around using the card as your guide.

STEP 10
12:11

Place the battery, without the magnet, in between the ends of the wire and like before, wrap it around the battery to create a hug.

STEP 11
13:10

Now, place the battery back onto the magnet and connect your wire around the battery and slide it down over the top of the magnet. Be sure to play with the shape of the wire if it doesn’t spin fast.

STEP 12
15:25

Want to make your wire spin the opposite direction? Simply flip the magnet on the bottom over, and your wire will start to spin the other way.

STEP 13
16:05

To make the last shape, the spiral, grab your syringe, place one end of a copper wire into the tip of the syringe and then wrap the wire around the outside. Finally, stretch the wire down to the 15 mark.

STEP 14
16:57

Next, at the end of the spiral, use your pliers to bend the end into a half circle so that it hugs your battery. You may need to adjust it to make it bigger or smaller as needed. If it still doesn’t spin, try giving it a little tap to get it started.

How It Works

Using a combination of copper wires and magnets we can witness the power of electricity and magnets working together to create an amazing spinning spectacle . By shaping our copper wires into different forms, we unlock the potential for unique and mesmerizing spinning effects. As the electric current flows through the wire, it generates a magnetic field around it. But that's not all—the magnet placed at the bottom also creates its own magnetic field. And just like magic, these magnetic fields interact with each other, causing a dance of repulsion or attraction depending on how the magnet is positioned.

This dynamic interaction between the electricity and the magnet is what sets the monopolar motor in motion. As they repel or attract each other, the spinning action begins, defying gravity and captivating our senses. With each passing moment, the motor spins, showcasing the wonders of electromagnetism. It's a delightful display of scientific principles in action—electricity and magnetism working together to bring motion to life.
