Question # 1

How can you use a magnetic field to separate isotopes of chemical elements?

  • Ans 1: Sinci isotopes of an elements have same charge number but different mass number.As we known that the radius of a charged particle inside a magnetic field is given as, r=mv/qB
    It shows that the isotopes projected from the same point at right angle to the magnetic field B will follow circular path of different radii due to their different masses,So they can be distinguished easily.

Question # 1

What is B non zero outside a solenoid?

  • Ans 1: The magnetic field outside a solenoid is not zero.This is only true for infinitely long solenoid.Infinitely long solenoid can not be found in nature,The magnetic field outside a real solenoid is less dense that inside the solenoid and often one is only concerned with the field inside,which is approximately constant.
