There is an electric current of I = 0.16 A flows through a long, straight wire. The wire lies in the plane of a rectangular area that has a pair of sides parallel to the wire. Refer to the diagram. The distance between the wire and the nearest side of the area is c = 0.021 m and the area’s dimensions are a = 0.012 m and b = 0.051 m, as shown. Please help in finding the magnetic flux, Φ, in T•m2, through the area.

Consider the two current-carrying wires in the figure. On the left is a long, straight wire carrying current I. In the same plane, there is a rectangular loop, which carries a current I2. The dimensions of the rectangular loop are shown in the figure, and the left side of the loop is a distance c from the wire. What are the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire? (Use any variable or symbol stated above along with the following as necessary: Ho, l, and a.) magnitude F = direction ---Select--

As shown in the figure, a long wire carries a current i₁ = 30 A and a rectangular loop carries current i₂ = 20 A. Take the dimensions to be a = 1 cm, b = 8 cm, and L = 30 cm. In unit vector notation, what is the net force on the loop due to i₁? i₁ ią L x

In the figure below, the current in the long, straight wire is I, = 7.00 A and the wire lies in the plane of the rectangular loop, which carries a current I, = 10.0 A.

A straight wire in a magnetic field experiences a force of 0.032 N when the current in the wire is 1.5 A. The current in the wire is changed, and the wire experiences a force of 0.074 N as a result. What is the new current?

A small current element at the origin has a length of 2.6mm and carries a current of 2.3A in the +z direction. Find the magnitude of the magnetic field due to this element at x= 2 m, y= 4 m, z = 0. Indicate its direction on a diagram.
