Understanding the operation of a Simple Electric Motor

Please see the following objectives of this activity:

To understand how electric motors work, the interaction of electrical energy with magnetic fields, and how these concepts are applied in real world devices.

Please complete the following materials for this activity:

Computer or tablet with internet access.
Access to the ck12 Interactive Simulation:

Simulation Link (Press to open)

Please read the following activity instructions:

Access the Simulation: Familiarize yourself with the virtual motor setup. The motor setup consists of a coil of wire (armature), magnetic field, and a power supply. Observe how the motor begins to rotate when the current is applied
Set Up the Experiment:
Start the Motor: Click the “Start” button and observe the coil’s rotation. Record the direction of rotation.

Change the Variables:
Current Strength: Adjust the current supplied to the motor. Observe how the motor’s speed and torque change.

Magnetic Field Strength:
Adjust the strength of the magnetic field.

Observe how the interaction between the magnetic fields influences
motor performance.

Number of Coils:
Experiment with the number of coils in the armature. Record the changes in the motor’s speed and torque when you add more coils.

Key Questions:

What happens to the speed of the motor when you increase the current?
How does the motor’s performance change when the magnetic field strength is altered?
How does adding more coils affect the torque and speed?

– POST-TEST –

As we conclude our lesson, it’s important to assess your understanding of the topic we’ve just explored. This step not only helps reinforce your new knowledge but also enables you to connect the concepts you’ve learned with your existing understanding. To assist in this, we’ve prepared a set of questions designed to gauge how well you’ve grasped the key points of the lesson. These questions are not a test, but a valuable tool to help both you—and us—assess your progress.

Take your time to reflect on each question and answer thoughtfully. There’s no rush—the goal here is not to get every answer right, but to give an honest and accurate snapshot of your current understanding.
This process will guide us in refining future lessons to better meet your learning needs, ensuring a more effective and enjoyable experience moving forward.

So, let’s continue on this journey of discovery! Ready? Let’s begin!
