Hint: The direction of the magnetic force in the moving charge is perpendicular to the plane made of v and B. Apply right hand thumb rule or Fleming's left hand rule to find direction.
Complete step by step solution:
The direction of the magnetic line produced by the direct current to the conductor is given by the law of the right hand palm rule. The law of the right hand states that to find the direction of the magnetic force at positive conduction charge, the thumb of the right hand points to V, the fingers point to B, and the force (F) is directed perpendicular to the palm of Right hand.
Additional Information:
When we talk about the current flowing in a wire, we are talking about the way in which positive charges are carried through the wire. Since we know that the current is just a moving charge, the wire will be affected by a magnetic field just like a single moving charge, but only when a current passes through it.
Note: There is a velocity, accordingly represented by the thumb. There are many field lines, represented by the fingers accordingly. Wherever the ball is, you press it with the palm of your hand. The pressure on the negative charge is just the opposite of the positive charge, Since the force is always perpendicular to the velocity vector, the pure magnetic field will not accelerate the charged particle in a single direction, but will create circular or helical motion (an idea explored in greater detail in future sections). It is important to note that the magnetic field will not exert any force on a static electric charge. These two observations follow the rule that magnetic fields do not work.
The lines of the magnetic field will be perpendicular to the flow of current on one side according to the "right hand rule" convention. The length of the region near the surface of the conductor will be the strongest, and will decrease as the distance from the conductor increases.
