Twelve wires of equal lengths are connected in the form of a skelton cube which is moving with a velocity `vecv` in direction of magnetic field `vecB`. Find the e.m.f. in each arm of the cube.

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 charged particle moves with velocity vecv in a uniform magnetic field vecB . The magnetic force experienced by the particle 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:

12 wires each of resistance r ohm are connected in the form of a skelton cube. Find the equivalent resistance of the cube, when a cell is joined across any one of the 12 wires forming the cube.

An electron is moving with an initial velocity vecv=v_0hati and is in a magnetic field vecB=B_0hatj . Then its de-Broglie wavelength

When a charged particle moving with velocity vecv is subjected to a magnetic field of induction vecB , the force on it is non-zero. This implies that

At which position of the rotating coil in the magnetic field, the induced e.m.f. is maximum?
