Question

To answer questions 1 and 2, please watch the video at the following ink: https://www.youtube.com/watch?v bkSsgTQOXVI Note: You may want to slow the pace of the video by clicking the settings icon at the bottom right corner of the video and select 0.25. Question 1 (3 points) Choose the correct options based on your observations of the video from 0:02 to 0:05 (Multiple options may be selected). Magnetic flux density remains constant Magnetic flux is increasing ds of the circular loop and the original magnetic flux are parallel Magnetic flux density increases as the separation between field lines increases D Induced and original magnetic flux are in opposite directions Motional emf is induced in the loop

Explanation / Answer

Hello,
          Please find the answer attached as under. Please give a thumbs up rating if you find the answer useful! Have a rocking day ahead!
1. In the video, clearly from 0.02 till 0.05, the magnetic flux is increasing (because of decrease between the magnetic flux lines). Hence option (2) is right.

2. In the mentioned parts of the video, the loop is rotating. Hence there will be induced voltage in the loop, because of which it will start to carry current. This current will produce a magnetic field by itself and a transformer emf will be generated. Hence options (1),(2) and (3) are right.

5. The right answer will be option (3) because it is mentioned that it is a source free regio. Hence there will be no current, but only charge.
