List of top Physics Questions on Motional Electromotive Force

A conductor is moving with a speed of $10 \text{ m/s}$ in the direction perpendicular to the direction of magnetic field of induction $0.8 \text{ T}$. If it induces an E.M.F. of $8 \text{ V}$ between the ends of the conductor, the length of the conductor is \dots

In the figure shown, the conductor PQ of length \(l\) is moved from \(x = 0\) to \(x = b\) and then up to \(x = 2b\) with a constant velocity \(\vec{v}\). A uniform magnetic field \(\vec{B}\) is perpendicular to the plane of the paper and extends from \(x = 0\) to \(x = b\) and it is zero from \(x>b\). The magnitude of emf induced in the conductor is

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 \( g \))

Figure shows a rectangular conductor PQRS in which the conductor PQ is free to move. The conductor PQ is moved towards the left with a constant velocity V as shown in the figure. Assume that there is no loss of energy due to friction. What will be the magnetic flux linked with the loop PQRS and the motional emf?
