Description: 【Metal Construction】: Crafted from quality metal, this teaching aid ensures practicality and longevity, providing a reliable resource for repeated classroom use 【Experiment Purpose】: Observe the phenomenon of the aluminum barrel rotating between the poles of the , and analyze the cause of this phenomenon 【Educational Tool for Electromagnetism Experiments】: This demonstrator is specifically designed to aid high school physics students in understanding the principles of electromagnetism, making complex concepts more accessible and engaging 【Experimental Principle】: The magnetic flux passing through the closed conductor changes, and there is an induced current in the closed conductor. The metal block is placed in the changing magnetic field to generate an induced current, which forms a closed loop in the metal itself 【Ideal for Classroom Demonstrations】: Electromagnetic Drive Demonstrator is suitable for teachers looking to enhance their physics curriculum with hands-on demonstrations that visually convey the dynamics of electromagnetic fields and rotations Specification: Material: Metal Size Chart: 18cmx12.5cmx24cm/7.09inchx4.92inchx9.45inch Package Includes: 1x Electromagnetic Drive Demonstrator Note: Please allow slightly errors 1-2cm/0.39-0.79inch differences due to manual measurement.
