A proton, moving north, enters a magnetic field of a certainstrength. Because of this field the proton curvesdownward. What is the direction of the magnetic field? A) upward B) towards the north C) downward D) towards the west E) towards the east Why/? A proton, moving north, enters a magnetic field of a certainstrength. Because of this field the proton curvesdownward. What is the direction of the magnetic field? A) upward B) towards the north C) downward D) towards the west E) towards the east Why/?
Explanation / Answer
the direction of magnetic field is towards the east Since from Fleming's left hand rule,if the middle , first ,thumb are streached perpendicular to each other then the firstfinger indicates direction of magnetic field ,middle fingerindicates motion of the particle then the thumb indicates force acton the particle .
