Question

Completed data sheets and graphs: Conceptual Questions (Due at the beginning of the next lab, must be typed) A small bar magnet drops through a coil. The magnet does not rotate during the fall. Assume that both the starting point and the end point are very far away from the coil. What is the initial magnetic flux in the coil? What is the final magnetic flux through the coil? What is the net change of the magnetic flux in the coil? Would the falling magnet induce any voltage in the coil? Does the induced voltage depend on the average magnetic flux change or on the instantaneous value of the magnetic flux change? A circular loop of wire is placed in a uniform, constant magnetic field. What orientation of the loop would have the maximum magnetic flux in the loop? For what orientation is the flux zero? Justify your answers.

Explanation / Answer

1) Initial flux = B*A

Final flux = -B*A

Change in flux = 2*B*A

Yes the falling magnet induces voltage

Voltage depends on average magnetic flux change

2) If the angle between the normal of the circular loop and the magnetic field is 0 or 180 degrees, then the flux would be maximum.

If the angle between  the normal of the circular loop and the magnetic field is 90, then the flux is zero.
