QUESTION #1 Motional EMF
A uniform magnetic field of 0.4 T acts perpendicular to a circular copper disc 20 ~cm in radius. The disc is having a uniform angular velocity of 10 π rad s⁻¹ about an axis through its centre and perpendicular to the disc. What is the potential difference developed between the axis of the disc and the rim? ( π = 3.14 )

QUESTION #21 Motional EMF
A conducting \bar moves on two conducting rails as shown in the figure. A constant magnetic field B \exists into the page. The \bar starts to move from the vertex at time t = 0 with a constant velocity. If the induced EMF is E ∝ tⁿ , then value of n is {{IMG1}}
