Question

Ions entering the uniform magnetic field region of a mass spectrometer have the same speed and charge. State and explain the effect on the path of the ions when the magnitude of he magnetic flux density is increased by 12%

Answer 1

you know that it will make circle or at least curve, so the curvature will increase or the radius of the circle will be decreased and area is the same so the magnetic field will be 1.12* B(old one).
F = qvB =mv^2/r.
