Day Nine:

 

Experiment #1: Flux

Apparatus: 

• Bed nails representing flux.
• Square wire representing surface.

We recorded the relationship between degree of the rectangle oriented vs. how many nails fit in the square wire.

The graph of flux(number of nails) vs. degree(radians). It looks like cosine graph. 

ActivPhysics

1. Area of the oval does not change the magnitude of the flux as long as the charge is inside the oval surface.

2. When the charge is outside the oval surface, the magnitude of the flux becomes zero.

3. When the sign of electric charge change, the sign of the flux is also change. 

When the magnitude of the electric charge is increasing/decreasing the magnitude of flux also increasing/decreasing.
