Problem 3

In Fig. 30-34, a 120- turn coil of radius 1.8 cm and resistance 5.3 1 is coaxial with a solenoid of 220 turns/cm and diameter 3.2 cm. The solenoid current drops from 1.5 A to zero in time interval 't ! 25 ms. What current is induced in the coil during 't?

Step-by-Step Solution:

Problem 3

In the below figure, a 120- turn coil of radius 1.8 cm and resistance 5.3 ohm, is coaxial with a solenoid of 220 turns/cm and diameter 3.2 cm. The solenoid current drops from 1.5 A to zero in time interval t = 25 ms. What current is induced in the coil during t?

                                 

                                                            Step by Step Solution

Step 1 of 3

Current change in solenoid causes change in the magnetic flux, which induces a current in the coil as it’s in the field of changing magnetic flux.

According to Faraday’s law, the total induced emf,

Substituting the given values,
