Two straight parallel wires, running north/south are separated by 12 cm and carry currents of 4 A in the same direction (north). Find the magnitude and direction of the magnetic field at a point midway between the wires. Now find the magnetic field 6 cm east of the "easternmost" wire. Also, calculate the force of one wire on the other. Is it attractive or repulsive?

statements concerning permanent magnets is false? The north pole of a permanent magnets is attracted to a south pole. All permanent magnets are surrounded by a magnetic field. The direction of a magnetic field is indicated by the north pole of a compass. Magnetic field lines outside a permanent magnet originate from the north pole and end on the south pole When a permanent magnet is cut in half, one piece will be a north pole and one piece will...

Two parallel long (infinite for our purposes) wires are oriented
along the z-axis. The figure below shows the
(xy)-plane perpendicular to the wires, including
the positions where the wires cross this plane. The wires carry
some unknown electric currents I1 and

Part A Determine the magnitude and direction of the force between two parallel wires 30 m long and 3.0 cm apart, each carrying 30 A in the same direction. The force on each wire will be attractive. The force on each wire will be repulsive. The wires will not interact. ----------------------- A long horizontal wire carries 23.0 A of current due north. The Earth's field 20.0 cm due west of the wire points north but downward, 45 ∘ below the...

Three infinite straight wires are fixed in place and aligned parallel to the z-axis as shown. The wire at (x,y) = (-22 cm, 0) carries current I1 = 3.1 A in the negative z-direction. The wire at (x,y) = (22 cm, 0) carries current I2 = 0.7 A in the positive z-direction. The wire at (x,y) = (0, 38.1 cm) carries current I3 = 6.3 A in the positive z-direction. 1. What is Bx(0,0), the x-component of the magnetic field...
