Motion of a Charged Particle in a Uniform Magnetic Field : Class12 Physics


 PHYSICS
CLASS-12
CBSE/ICSE/IB BOARD/BSEB(BIHAR BOARD)/IIT-JEE/NEET
LECTURE-12
CHAPTER: MAGNETIC EFFECT OF CURRENT
MOTION OF A CHARGED PARTICLE IN A UNIFORM MAGNETIC FIELD :
Motion of a charged particle in a uniform magnetic field
1. Lorentz magnetic force
2.Trajectory of charged particle                                                                                                  3.Three cases arise :
(a)when charged particle is moving along the direction of magnetic field i.e. angle between velocity and magnetic field is zero
(i) Expression for Lorentz force
(ii)Trajectory of particle
  (b)When charged particle is moving perpendicular to the direction of magnetic field 
        i.e. the angle between velocity and magnetic field is 90 degree
         (i) Trajectory of particle
          (ii)Expression for Lorentz force
           (iii)Expression for centripetal force
           (iv)Expression for radius
            (v)Expression for velocity
            (vi)Expression for angular frequency/angular velocity
            (vii)Expression for frequency
            (viii)Expression for time period
            (ix)Expression for kinetic energy
(c)When the angle between velocity of charged particle and magnetic field < 90 degree
   (i) Trajectory of particle
          (ii)Expression for Lorentz force
           (iii)Expression for centripetal force
           (iv)Expression for radius
            (v)Expression for velocity
            (vi)Expression for angular frequency/angular velocity
            (vii)Expression for frequency
            (viii)Expression for time period
            (ix)Expression for kinetic energy

    I have been publishing a set of the most important topics since 8 Jan.2021 for students of class-12 Physics preparing for CBSE BOARD/ICSE BOARD/BSEB( BIHAR BOARD )/IIT-JEE/NEET .It is one of them. Compare my lecture with other. If it is better than other ,learn it and score marks -5/5.
    Thank you
