A synchrotron uses a combination of solenoid and toroid to generate high magnetic fields. Charged particles like electrons and protons can be accelerated to very high energies using a synchrotron. A synchrotron adjusts the magnetic field such that the particles are kept in a circular orbit. It is used to study high-energy particle collisions.
(a)
If the magnetic field is parallel to the positive Y-axis and the charged particle is moving along the positive X-axis, which way would the Lorentz force be for: (i) an electron, (ii) a proton.
(b)
An electron does not suffer any deflection while passing through a region of uniform magnetic field. What is the direction of the magnetic field?
