Chapter 13
Question 1 | What is the force that a conductor of length L carrying a current I experiences when placed in a magnetic field B? What is the direction of this force? See answer |
Question 2 | What is the nature of force between two parallel current carrying wires (in the same direction). See answer |
Question 3 | What is the magnitude of the force on a charge q moving with a velocity v in a magnetic field B? See answer |
Question 4 | In a uniform magnetic field B, an electron beam enters with velocity v. Write the expression for the force experienced by the electrons. See answer |
Question 5 | What will be the path of a charged particle moving in a uniform magnetic field at any arbitrary angle with the field? See answer |
Question 6 | An electron does not suffer any deflection while passing through a region. Are you sure that there is no magnetic field? See answer |
Question 7 | An electron beam passes through a region of crossed electric and magnetic fields of intensity E and B respectively. For what value of the electron speed the beam will remain unaffected? See answer |
Question 8 | Uniform electric and magnetic fields are produced in the same direction. An electron is projected in the direction of the fields. What will be the effect on the K.E of the electron due to the fields? See answer |
Question 9 | What is cyclotron frequency of a charged particle q, of mass m moving in a magnetic field B? See answer |
Question 10 | Can neutron be accelerated in a cyclotron? Give reason. See answer |
Question 11 | A current carrying loop, free to turn, is placed in a magnetic field B. What will be its orientation relative to B in the equilibrium state? See answer |
Question 12 | How does a current carrying wire behave like a bar magnet? See answer |
