Question # 1

How can a current loop be used to determine the pressure of a magnetic field in a given region of space?

  • Ans 1: The torque is experienced by a current carrying loop when placed in magnetic field is t=NIBA cos alpha.
    If the loop is deflected in a given region,then it confirms the presence of magnetic field otherwise not.

Question # 1

Two charged particle are projected into a region where there is a magnetic field perpendicular to their velocities.if the charge is deflected in opposite directions,what you can say about them?

  • Ans 1: When a charged particle is projected in a magnetic field,it will experience the magnetic force.The magnetic force is a deflecting force,Thus if the charged particle are deflected in opposite direction,then particle are oppositely charged i.e. one particle is positively charged and the other is negatively charged.
