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?
Two long parallel wires are hung by cords of length 4.00 cm, as shown in the figure. Each wire has a mass per unit length of 30.0 g/m and they carry the same current in opposite directions. What is the current if the cords are at a angle with respect to the vertical?
The two long parallel wires shown in the figure carry currents in the same direction. If A and A, where cm, what is the magnetic field at point ?
