ANSWER: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,
