Lesson: The Magnetic Force between Parallel Constant CurrentsPhysics
In this lesson, we will learn how to calculate the magnetic force between two parallel current-carrying wires.
Sample Question Videos
Two long, straight wires are parallel and 10 cm apart. One carries a current of 2.0 A, the other a current of 5.0 A. What is the magnitude of the force per unit length between the wires?
The two long parallel wires shown in the figure carry currents in the same direction. If and , where , what is the magnetic field at point ?
The figure shows two long, straight, horizontal wires that are parallel and a distance apart, where . Both wires carry a current , but in opposite directions.
What is the magnitude of the magnetic field at ?
