Answer:

2 one option it is very simple question by the way

Answer 2

Answer:

The correct option is 4.

Explanation:

• We have to use Fleming's Left-hand rule for this problem.
• According to Fleming's Left Hand Rule, if the thumb, forefinger, and middle finger are arranged in a straight line on the left hand, the thumb will point in the direction of the force experienced by the conductor, the forefinger will point in the direction of the magnetic field, and the middle finger will point in the direction of the electric current.
• This rule is employed to determine the magnetic force's direction within an electric motor.
• An electric charge, an electric current, and magnetic materials are all affected magnetically by a magnetic field, which is a vector field.
• A force perpendicular to the charge's own velocity and the magnetic field acts on it when the charge is travelling through a magnetic field.

The rod will thus move out of the field.
