第二篇:Physics Experimental Report【Electromagnetic induction】 高中物理电磁感应实验报告
Physics Experimental Report
Group members:
Name and Purpose
Name: Electromagnetic induction
Purpose: To find the relationship between a changing magnetic field and its induced current.
Experiment Equipment
A galvanometer
A magnet
Coil of wire
Principle
Faraday’s law, Lenz’s Law
Experimental Process
1. Connect all the staffs
2. Moving the north of magnet up toward the coil quickly, and then change the direction (South up towards the coil)
3. Moving the magnet with different velocity
4. Observe and record the data
Result and Conclusion
The relative motion of the magnet and the coil can induce an emf. Whether the galvanometer’s readings are to the left or right on which side of magnet is moving up or down. And the induced current is opposite when the magnet is moved away from the coil.
Experimental Error
At first, we connect the equipment wrong as the photo on the right
so that our result was totally opposite to the proper experiment.
And this kind of mistakes should be avoided in the future.
