MOTION OF ELECTRON IN MAGNETIC FEILD

motion of electron longitudinal to uniform magnetic field

An electron of velocity V enters in uniform magnetic field of strenght,the magnetic feild acting on electron is given, F=0 (sinA=0 [angle=0*])

motion of electron perpendicular to uniform magnetic field

motion of electron in trensverse magnetic field B and it is entered with velocity V,therefore F=eVB (sinA=90)

formulas obtained

radius of electron R=mV/eB

time period T=2*3.14*m/eB

Angular velocity w=eB/m

Motion of elctron at acute angle or Helical Path in magnetic field.

An electron is moving with velocity V in uniform magnetic field with angle A and the magnetic field acting in components(X and Y).

formulas obtained

radius of electron R=mVsinA/eB

Pitch T=2*3.14*mV*cosA/eB

Magnetostatic deflection

D=LlB(e/2mVa)^1/2

magnetic deflection sensitivity S=D/B

Deflection Factor = reciprocal of magnetostatic deflection sensitivity.

Bethe's Law

when an electron in uniform magnetic feild move from lowedr potential to higher potencial,electron gets accelerated and bented towards the normal.

sinA/sinB=V1/V2=(potential deference 1/potential deference 2)^1/2.
