Electromagetic effects
- 1. Lets watch a video clip…
- 2. Is there a battery source? What is that “piece of thing” that the person is holding? Why is there a current?
- 3. Electromagnetic Effects Phenomenon of inducing an emf in a circuit due to a changing magnetic field.
- 6. Factors affecting the magnitude of the induced emf Greater deflection Insert N pole of 1 bar magnet into solenoid with twice the number of turns Greater deflection Insert N pole of 2 bar magnets into solenoid Greater deflection Insert N pole of 1 bar magnet into solenoid at twice the speed Slight deflection Insert N pole of 1 bar magnet into solenoid Galvanometer response Procedure
- 9. Deflection to the left Solenoid move towards N pole of magnet Deflection to the right Solenoid withdraw from the same magnet Deflection to the left Withdraw the same bar magnet out of solenoid Deflection to the right Insert S pole of 1 bar magnet into solenoid Deflection to the right Withdraw the same bar magnet out of solenoid Deflection to the left Insert N pole of 1 bar magnet into solenoid Galvanometer response Procedure
