Question

In the experiment of inductance, the magnet is dropped passing through a solenoid. When the magnetic flux is the maximum on the solenoid during the process? When the magnet begin to drop When the magnet just go into the solenoid When the magnet is at the middle of the solenoid When the the magnet just leave the solenoid You need to create the graph of the induced emf as a function of time. To get enough point for the graph, what is suitable rate you should set for the voltage probe records measurement at frequency? (How many data you should get in one second?) 10 Hz 50 Hz 100 Hz 500 Hz

Explanation / Answer

Question 1:- when the magnet is at the middle of solenoid

So answer is C

Question 2:- B 50 hz because this is the frequency of alternating voltage supply.
