The circle is centered on a long straight wire; at time t = 0 the current in the long straight wire is 10 rightward. Thereafter, the current changes according to i =10 A + 5 (The straight wire is insulated; so there is no electrical contact between it and the wire of the loop.) What is the magnitude of the current induced in the loop at times t > 0 .

A long copper wire carries a current of I ampere. Calculate the magnetic flux per meter of the wire for a plane surface S inside the wire as shown in Fig. A wire forms a closed circular loop of radius = 1 m and resistance 5 ohm . The circle is centered on a long straight wire; at time t = 0 the current in the long straight wire is 10 rightward. Thereafter
