(c) When loop is entering in the field, magnetic flux (i.e. ?) linked with the loop increases so induced emf in it \(e = Bvl\)=\(0.6 \times {10^{ - 2}} \times 5 \times {10^{ - 2}} = 3 \times {10^{ - 4}}V\) (Negative) .
When loop completely entered in the field (after \(5\, sec\)) flux linked with the loop remains constant so \(e = 0.\)
After \(15\, sec\), loop begins to exit out, linked magnetic flux decreases so induced emf \(e = 3 \times {10^{ - 4}}V\) (Positive).
