Explain the main functions of electric and magnetic fields in a cyclotron.

Draw a schematic diagram of a cyclotron. Explain its underlying principle and working, stating clearly the function of the electric and magnetic fields applied on a charged particle. Deduce an expression for the period of revolution and show that it does not depend on the speed of the charged particle.

(a) Draw a schematic sketch of a cyclotron. Explain clearly the role of crossed electric and magnetic field in accelerating the charge. Hence derive the expression for the kinetic energy acquired by the particles. (b) An alpha -particle and a proton are relased form the centre of the cyclotron and made to accelerate. (i) Can both be accelerated at the same cyclotron frequency? Give reason to justify your answer. (ii) When they are accelerated in turn, which of the two will have higher velocity at the exit slit of the dees ?

The electric and magnetic field of an electromagnetic wave is

An electron beam produces i) Electrical field around the beam ii) Magnetic field around the beam iii) Electrical field is more stronger than the magnetic field iv) Electrical and magnetic fields are not produced

The law which states that the variations of electric field causes magnetic field is

STATEMENT-1 : Ratio of magnitudes of electric field magnetic field in an electromangnetic wave is constant. STATEMENT-2 : Electric field and magnetic field are always is same phase in an electromagnetic wave.

A proton moves at a constant velocity of 50 m/s along the x-axis, in uniform electric and magnetic fields. The magnetic field is B = (2.0 mT)hatj . What is the electric field?

The amplitudes of electric and magnetic fields are related to each other as
