A conducting loop is placed in a magnetic field, normal to its plane. The magnitude of the magnetic field varies with time as shown in the figure. If \(\varepsilon_1, \varepsilon_2\) and \(\varepsilon_3\) are magnitudes of induced emfs during periods \(0 \leq {t} \leq {T}\) , \({T} \leq {t} \leq 2 {~T}\) and \(2 {~T} \leq {t} \leq 3 {~T}\) , then:
- \(\varepsilon_1>\varepsilon_2>\varepsilon_3\)
- \(\varepsilon_2>\varepsilon_3>\varepsilon_1\)
- \(\varepsilon_3>\varepsilon_1>\varepsilon_2\)
- \(\varepsilon_1>\varepsilon_3>\varepsilon_2\)
Answer
(D) _1> _3> _2
