Question
In a particular wire in a circuit, electrons flow in the $+z$ direction. What is the direction of conventional current in the wire?
Step 1
Electrons are negatively charged particles, so they flow in the opposite direction of the electric field. In this case, since electrons flow in the $+z$ direction, the electric field must be in the $-z$ direction. Show more…

If If electrons are flowing clockwise around an electric circuit, which way is the conventional current flowing in the circuit?
A wire carries a current along the $+z$ direction and experiences a force along $-y .$ If the magnetic field is perpendicular to the wire, what is the direction of $\vec{B}$ ?

Magnetic Force on an Electric Current
A long, straight wire lying along the $x$ -axis carries a current, $i$ flowing in the positive $x$ -direction. A second long, straight wire lies along the $y$ -axis and has a current $i$ in the positive $y$ -direction. What are the magnitude and the direction of the magnetic field at point $z=b$ on the $z$ -axis?
