For a velocity selector for ions using perpendicular electric and magnetic fields is mathematically given as

B= 0.225 T

What magnetic field would allow the selection of a velocity of 4000 m/s?

Generally, the equation for the magnetic field is mathematically given as

B = E/v

Therefore

B = 900/4000

B= 0.225 T

In conclusion. the magnetic field is

B= 0.225 T
