Question 1

Experiment with the tubes: Which one would fall the fastest/slowest in copper, plastic or copper with cut?

Answer 1

1. The magnet with the copper tube would take the longest

Question 2

Why does the magnet experience slowness in the copper tube?

Answer 2

The magnet falls through the copper tube it will experience an increase in flux just below the magnet and a decrease in flux just above the magnet

Question 3

As the magnet falls, what is induced?

Answer 3

Eddy currents (horizontally), where the eddy currents will swirl in a direction that creates a magnetic field directed upwards below the magnet and a magnetic field directed downwards above the magnet by Lenz’s law.

Question 4

What effect would be produced when the magnet is in the tube?

Answer 4

The flux repels the magnet’s North pole upwards, and also attracts the magnet’s south pole upwards as it falls which will slow down

Question 5

Will plastic be conductive?

Answer 5

No because it is not conductive, so eddy currents can not induced.

Question 6

Why will the slit in the copper tube not induce eddy currents?

Answer 6

It will induce currents but not large eddy currents will be formed.

Question 7

Will the magnets take the exact same time for them to fall?

Answer 7

The magnets will take approx. the equal times to fall through the plastic tube and copper tube with the accelerating at 9.8m/s^2.
