A conductor of length T'is rotated about one of its ends at a constant angular speed 'omega' in a plane perpendicular to a uniform magnetic field B. Plot graphs to show variations of the emf induced across the ends of the conductor with (i) angular speed o and (ii) length of the conductor i. |

Answer» Solution :When a conductor of length " is rotated about one of its ends at a constant angular speed .`OMEGA`. in a plane perpendicular to a uniform magnetic field "B., the induced EMF `epsilon` across its ends is given as : `epsilon = (1)/(2) B I^(2) omega` It means that (i) `epsilon PROP omega` and (II) `epsilon prop I^(2) ` . Hence `epsilon- omega` and `epsilon-l` graphs are as shown below :
