are out-of-page while one current is into the page. What is the magnitude and direction of the magnetic field at the center of the square? Express it in unit vector notations. = Three conductors carrying identical parallel currents I (=10.0A) are arranged on the three vertices of a square of edge length a (=5.0cm) of the as shown in the figure. Two of the currents 1 a 3.

A particle of mass 8.1 × 10-8 kg and charge +5.4 µC is traveling due east. It enters perpendicularly a magnetic field whose magnitude is 3.5 T. After entering the field, the particle completes one-half of a circle and exits the field traveling due west. How much time does the particle spend in the magnetic field? Number i Units

See McKi In the figure, four long straight wires are perpendicular to the page, and their cross sections form a square of edge length a = 17.5 cm. Each wire carries 7.50 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3. In unit-vector notation, what is the net magnetic force per meter of wire length on wire 4? H Number + Units

In the figure below, four long straight wires are perpendicular to the page, and their cross-sections form a square of edge length a = 10.5 cm. Each wire carries 8.00 A, and the currents are out of the page in wires 1 and 4 and into the page in wires 2 and 3. What is the magnitude and direction of the net magnetic force per meter of wire length on wire 4? magnitude      N/m direction      ° (counterclockwise from the positive x-axis) (please show units. It really helps me out)
