Question

Two current carrying wires are separated by 5.00 cm. They carry the same 4.00 A current and point to the same direction.

a. What kind of force is between them, repulsive or attractive?

b. What is the magnitude of magnetic field established on one wire from the other current carrying wire?

c. What is the magnitude of force per length on each wire?

d. What is the magnitude of the magnetic field at a point located 20.0 cm above the bottom wire and 15.0 cm above the top wire?

Answer 1

I I= I2 = 40 d=5cm Iz @ for the parallel Current Carrying weres, the force is of attractive nature. for anteparalled current carrying wires, et is repulsive- magneter feeld upper current in the lower were on the heire due to BE Yo Iz and B = Yo Jy 2nd taxo7 x 4 za x5x10-2 B = 1-6X165T - 16 YT force per unit length df So I Iz 644H /m de 2nd
