A wire of length 0.1 m moves with a speed of `10 m s^-1` perpendicular to a magnetic field of induction `1 Wb m^-2`. What is the value of induced e.m.f.?

What is the basic cause of induced e.m.f.?

A straight line conductor of length 0.4 m is moved with a speed of 7ms^-1 perpendicular to magnetic field of intensity 0.9 Wb m^-2 . The induced e.m.f. across the conductor is

A two metre wire is moving with a velocitu of 1m//s perpendicular to a magnetic field of 0.5 Wb//m^2 . the emf induced in it will be:

A two metre wire is moving with a velocity of 1 m/s perpendicular to a magnetic field of 0.5 Wb/m^2 . The emf induced in it will be

A wire 88cm long bent into a circular loop is placed perpendicular to the magnetic field of density 2.5 Wb m^(-2) . Within 0.5 s the loop is changed into square of each side 22 cm and the density is increased to 3Wbm-2 . Calculate the value of e.m.f. induced.

A straight conductor of length 4 metres move at a speed of 10 m/sec when the conductor makes an angles of 30^@ with the direction of magnetic field of indcution 0.1 Weber per meter^2 . Then the induced e.m.f. is

The given figure SAQ 35 shows the positions of a loop PQR in a perpendicular uniform magnetic field. In which position of the coil there is an induced e.m.f.
