T12:30 758 Time Dependent Current in a Wire 123456 An infinite straight wire carries a current I that varies with time as shown above. It increases from 0 at t = 0 to a maximum value I, - 5.4 A at t-t₁-18 s, remains constant at this value until t-t₂ when it decreases linearly to a value 4-5.4 A at t = t4 = 35 s, passing through zero at t = t3 = 29 s. A conducting loop with sides W = 36 cm and L = 76 cm is fixed in the x-y plane at a distance d - 50 cm from the wire as shown.
