The permanent magnet DC motor with Cobra SMARTsense

Principle

Electric motors for not too high power and simple dynamos are often based on the principle that an electromagnet rotates in the field of one (or more) permanent magnets.

Benefits

• Particularly comprehensible and didactically prepared description of experiments (reference to everyday life, etc.) incl. protocol questions.
• Teach in a future-oriented way: Integration into digital science lessons with tablets or smartphones.
• Increased motivation among students through use of the intuitive measureAPP.
• Increased media literacy.
• No additional cable connections between the modules necessary - clearer and faster set-up.
• contact reliability due to puzzle-like interlocking building blocks
• Hard gold-plated, corrosion-resistant contacts
• Double learning success: electrical circuit diagram visible on the upper side and real components on the lower side

Tasks

Investigate the behavior of the motor model on which a permanent magnet is placed.

Learning Objectives

With the aid of the model of a permanent magnet DC motor, the students should learn about the basic design and operation of an electric motor.
