Give a short response to the following questions 1. A compass needle is deflected when a charges plastic rod is held near it. What is the origin of the force that produces the deflection? 2. What is the difference between permeability and permittivity? 3. Can the objects in rotational motion create a magnetic field? Provide an example. Electron and proton are projected with the same velocity normal to the magnetic field. Which one will suffer 4. greater deflection? Why? A charged particle moves in a straight line through a particular region of space, Could there be a non-zero 5. magnetic field in this region? 6. If a current is passed through an unstretched spring, will the spring contract or expand? 7. How can neutrons be accelerated in a cyclotron? A current carrying loop, free to turn, is placed in a uniform magnetic field B. What will be its orientation 8. relative to B, in the equilibrium state? 9. How does a current carrying coil behave like a bar magnet?
