Two metallic wires lying parallel, If the current in these wires is flowing in the same direction, the wires will
Correct answer: A. attract each other
- A. attract each other
- B. repel each other
- C. have no force of attraction or repulsion
- D. remain stationary
Explanation
Parallel wires with current in the same direction exert attractive forces on eachother.

About Magnetic Flux Density
Magnetic flux density measures the magnetic force acting on a current carrying conductor or moving charge in a magnetic field. Work includes the relations B equals F divided by IL and F equals qvB, the tesla as its SI unit, field direction and the distinction between flux density and magnetic flux.
