We set up two parallel currents in the same direction. Which describes the magnetic force on each wire due to the other wire?
A. The force on each current is perpendicular to the current and away from the other current.
B. The force on each current is in the direction opposite that of the current.
C. The force on each current is in the direction of the current.
D. The force on each current is perpendicular to the current and toward the other current.
The rate at which the electric charge moves in the conductor is termed as current and can be determined by using Ohm's law. The electric current flows in reverse direction to the flow of charges.
Answer and Explanation:
According to the question, it is said that the direction in which current is flowing is the same. So, the magnetic fields produced due to these currents will be in the opposite direction. When the direction of the magnetic field is opposite, this will result in the generation of force to be attractive in nature.
Therefore, option (d) is correct.
The force on each wire will be perpendicular and toward the other wire.
