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 l = 4.9 A att t-15s, remains constant at this value until t-t when it decreases linearly to a value 14-4.9 A at t-4-26 5, passing through zero at t-t3-23 s. A conducting loop with sides W-26 cm and L = 78 cm is fixed in the x-y plane at a distance d- 57 cm from the wire as shown. I(t) W d +I I I4 t 1) What is the magnitude of the magnetic flux through the loop at time t-t-15 s T-m Submit 2) What is t, the induced emf in the loop at time t-7.5 s? Define the emf to be positive if the induced current in the loop is clockwise and negative if the current is counter-clockwise.
