Why cannot the B-field of an infinitely long straight current-carrying conductor have a component in the direction of the current?

As induced magnetic lines exist in a plane perpendicular to the direction of flow of current, the component in the direction of current i.e cos 90 component will be zero. Recall cos 90 = 0. Hence the answer

What simple rule has been established for finding the direction of magnetic force around a current-carrying conductor?
The right hand rule. If you were to place your right hand around the conductor, with the thumb pointing in the direction of current flow, your fingers which are wrapped around the conductor will point in the direction of magnetic flux. Said another way, if you are looking at the end of the conductor and current is flowing towards you, then magnetic flux will be counter-clockwise.
How is it used in determining the direction of the magnetic field around a conductor carrying current?
By using right hand rulee.. how?? let me explain.. first you should be knowing the direction of flow of current, then hold the current carrying conductor by your right hand in a way that your thumb points the direction of current flowing and curl your fingures around the conductor the manner your figures curl around condutor would determine the the magnetic field's direction that may be clockwise or anti-clockwise..thankkxx.
To use your left hand to derermine the direction of the voltage developed in a moving conductor in a stationary magnetic field ou must point your?
The answer choices weren't provided. To use your left hand to determine the direction of the voltage developed in a moving conductor in a stationary magnetic field you must point your forefinger in the direction of the lines of force.
Why does the current carrying conductor experiences a force when it is placed in magnetic field state Fleming's left hand rule?
The force on current carrying conductor kept in a magnetic field is given by the expression F = B I L sin@ So the force becomes zero when the current carrying conductor is kept parallel to the magnetic field direction and becomes maximum when the current direction is normal to the magnetic field direction. Ok now why does a force exist on the current carrying conductor? As current flows through a conductor magnetic lines are formed aroung the conductor. This magnetic field gets interaction with the external field and so a force comes into the scene.
A current flowing towards the viewer in a cross section conductor is shown by?
Sketch the direction line of force around a conductor which is carrying current away from the viewer and also towards the viewer.
