    A two metre wire is moving with a velocity of 1 m/s perpendicularly to a magnetic field of 0.5 weber/\[{{m}^{2}}\]. The emf induced in it will be:

    A)  0.1 volt                

    B)  0.25 volt

    C)  0.75 volt                             

    D)  1 volt

    Correct Answer: D

    Solution :

    Using formula for induced emf \[e=B\upsilon l\]                              ...(i) Here, magnetic field \[=0.5wb/{{m}^{2}}\] Velocity v = 1 m/s Length of the wave = 2 m Putting these values in equation (i) we have \[e=0.5\times 1\times 2=1\,volt\]
