In an electron accelerator - betatron - the role of accelerating voltage is played by the induced emf, excited by a change in the magnetic flux penetrating the electron's orbit. At the same time, electrons move in orbits of approximately constant radius. Determine the relationship necessary for this between the average magnetic field (B)(t) penetrating the electron’s orbit and the magnetic field B0(t) directly in the orbit. The field is considered normal to the orbital plane.
