electrostatic energy stored between the plates increases
vi) An electron moves in a magnetic field of IT with velocity 5.0 * 109 ms' in the direction of
the magnetic field. The magnitude of the force experienced by the electron is 95% 10-N
VII) Gauss's law for magnetism suggests that magnetic monopoles exist
Magnetisation of a paramagnetic material attains a saturation value at very low
temperatures and high magnetic fields
