A metal rod `1.5m` long rotates about its one end in a vertical plane at right angles to the magnetic meridian. If the frequency of rotation is `20 rev s^(-1)`, find the emf induced between the ends of the rod `(B_(H) = 0.32G)`.

A metal rod of length lm, rotates about its one end in a plane at right angles to a horizontal magnetic field of induction 7/22xx10^-4T If the frequency of rotation is 10Hz, then the magnitude of induced emf is

A metal rod of length L meter rotates about one end in a vertical plane at right angles to the magnetic-meridian. Frequency of revolution is f Hz.If the horizontal component of Earth's magnetic field is H Tesla then find the expression of inducted emf between the ends of the rod.

A metal rod of length 1m, rotates about its one end in a plane at right angles to a horizontal magnetic field of induction 7/22 xx 10^(-4)T . If its frequency of rotation is 10 Hz, then the magnitude of induced e.m.f. Is

A metal rod of length 1m is rotated about one of its ends in a place at right angle to a uniform magnetic field of induction 5xx10^(-3) T. if it makes 1800 rotations per minute, then the emf iniduced between its ends is

A metal rod 1/ (sqrt(pi)) meter long rotates about one of its ends perpendicular to a plane whose magnetic induction is 4xx10^-3T . Calculate the number of revolutions made by the rod per second if the e.m.f. induced between the ends of the rod is 16mV.

A metal rod of length 1 m is rotated about one of its ends in a plane at right angles to a uniform magnetic field of 2.5xx10^(-3)(Wb)/m^2 . If itmakes 30rps, calculate the induced emf between its ends.
