A closed coil having 20 turns 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 square wire loop with L= 1 m sides is perpendicular to a uniform magnetic field 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
