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 figure shows two long straight horizontal wires that are parallel and a distance apart, where cm. Both wires carry a current A but in opposite directions.
What is the magnitude of the magnetic field at ?
What is the magnitude of the magnetic field at
Two long straight wires are parallel and 65 cm apart. If each wire carries a current of 80 A in the same direction, what is the magnetic force per unit length exerted on each wire?
