A proton moving vertically downward enters a magnetic field pointing towards north. In which direction proton will deflect?
Correct answer: A. East
- A. East
- B. West
- C. North
- D. South
Explanation
Option A is correctProton will represent the direction of current. So, the direction of current is vertically downward. According to Fleming's left hand rule, if middle finger represents the direction of current and fore-finger represents the direction of magnetic field then thumb will represent the direction of Lorentz force acting on the proton which deflects the proton in east direction.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
