Answer 2

Answer:

If we point our pointer finger in the direction the positive charge is moving, and then our middle finger in the direction of the magnetic field and our thumb points in the direction of the magnetic force pushing on the moving charge. This is known as the Fleming's right hand thumb rule.

Right hand thumb rule: Imagine that you are grasping the current carrying wire with your right hand such that your thumb is pointing in the direction of the current.Then the direction of your curled fingers will give the direction of the magnetic field produced by the current.
