The EMF of induction arising in a closed loop, if the magnetic flux penetrating the loop
| February 9, 2021 | education
The EMF of induction arising in a closed loop, if the magnetic flux penetrating the loop, evenly decreases from 10 Wb to 2 Wb in 2 s, is numerically equal to …
According to Faraday’s law, the EMF of induction is directly proportional to the change in the speed of the magnetic flux.
Faraday’s formula is as follows: E = – Δφ / Δt,
where Δφ is the change in magnetic flux;
Δt is the time interval during which the magnetic flux changes.
E = – (2 – 10) / 2 = 8/2 = 4 V.
Answer: EMF of induction is 4 V.
