List of top Physics Questions on Motional Electromotive Force asked in MHT CET

A wire of length \( L \) and resistance \( R \) is falling vertically through Earth's horizontal magnetic field \( B \). What is the current induced in the wire when it has fallen a height \( L \)? (Take acceleration due to gravity as \( g \))

A metal conductor of length $1\ \text{m}$ rotates vertically about one of its ends at an angular velocity of $5\ \text{rad/s}$. If the horizontal component of earth's magnetic field is $0.2 \times 10^{-4}\ \text{T}$, then the emf developed between the two ends of the conductor is

A straight conductor of length 0.6 m is moved with a speed of 10 $\text{ms}^{-1}$ perpendicular to a magnetic field of induction 1.2 $\text{Wb/m}^2$. The induced e.m.f. across the conductor is
