An isotope 24Mg moves through a velocity selector of a mass spectrometer has an electric field of 150 Vcm-1 and a magnetic field of 0.70 T. Calculate the velocity of the isotope that exits the velocity selector.
A plane of two turns coil of area 0.0127 m2 is placed in a uniform magnetic field of 0.7 T. The current in the coils is 3 A. If the plane makes an angle of 50° with the magnetic field, calculate the torque exerted on the coil.
An electron moves in a uniform magnetic field. At a particular instant the speed of the
electron is 3.0x10^(6) m/s and the magnitude of the magnetic force acting on it is
5.0x10^(-13) N. The velocity of the electron makes an angle of 30o with the direction of
the magnetic field. Calculate the magnetic field strength at that instant.
