Question

A) Determine the magnitude and direction of the force between two parallel wires 35mlong and 4.0cm ? apart, each carrying 35Ain the same direction.

Determine the magnitude and direction of the force between two parallel wires 35m long and 4.0cm ? apart, each carrying 35A in the same direction. Determine the magnitude of the force between two parallel wires. Express your answer to two significant figures and include the appropriate units. A long pair of insulated wires serves to conduct 25.0Aof dc current to and from an instrument. If the wires are of negligible diameter but are 2.8 mm apart, what is the magnetic field10.0 cm from their midpoint, in their plane (Figure 1)?

Explanation / Answer

a) F = u * I1 ** I2/ (2pi * l) * lenght

F = 4pi * 10^(-7) *35*35 * 35 / (2 * pi * 0.04)

F = 0.214N
