168 Electromagnetic Induction 6 If the current in long straight current carrying wire increases with the time then direction of induced current in circular loop is 1 Clockwise 2 Anticlockwise 3 First clockwise and then anticlockwise 4 First anticlockwise then clockwise In the given figure shown below a conducting circular loop of radius T is placed in a uniform and perpendicular magnetic field B A metal rod OA is pivoted at centre O of the loop The other end A of rod touches the loop The rod OA and loop are resistanceless but a resistance R is connected between O and fixed point e of loop The rod is rotated with angular velocity w The current in resistance R is
