Question

hi frnds good mornings to all. the peson who answer correctly i will chat. 20 pts in class 10. . . magnetic effects of electric current. 1.a positively charged particle (alpha) projected towards west is deflected towards north by magnetic field.state the rule used for finding the correct direction

Answer 1

As the direction of current is towards west and force is towards north so by Flemming’s Left Hand Rule, the direction of magnetic field is upward. The rule used is Flemming’s Left Hand Rule which states that if we strech our thumb, forefinger, and middle finger of our left hand perpendicular to each other in such a way that fore finger points the direction of magnetic field and middle finger points the direction of current then thumb will represent the direction of force.
