3) A square loop of dimensions 15.0 cm x 15.0 cm carries a current of 4.0 A as shown in the figure below. A long straight wire parallel to x-axis at z=9.0 cm, carries a current of 15A. a) What is the total force on the wire loop due to the current in the straight wire? b) Is there any torque in the loop? If so, calculate it.

Two long, parallel wires separated by 2.95 cm carry currents in opposite directions. The current in one wire is 1.45 A, and the current in the other is 3.20 A. (a) Find the magnitude of the force per unit length that one wire exerts on the other. 1.572e-5 Your response differs from the correct answer by more than 10%. Double check your calculations. N/m

In theory, a current carrying wire will have a magnetic field. What are various ways to run a current through wire? How can you tell you have a magnetic field? What tests could you do?

In the figure below, the blue wire has a current I = 34 A and the red loop is a square with sides that are 45 cm long. The distance between the blue wire and wire AB is 2.6 cm. Determine the force the blue wire exerts on wire AB and the force the blue wire exerts wire CD.

Two long parallel wires carry currents of 3.39 A and 4.13 A. The magnitude of the force per unit length acting on each wire is 5.33 x 10-5 N/m. Find the separation distance d of the wires expressed in millimeters. d = mm

Consider a long, horizontal Large Wire with current of 10 A running through it. We want to levitate a horizontal, thin, 0.50 m length of wire above it. If the thin wire has a mass of 10 grams, and a current of 300 mA, how far above the Large Wire will it hover (net force of zero) due to magnetic and gravitational forces? A. If the thin wire hovers above the Large Wire due to their magnetic fields, are their currents going the same direction, or opposite directions. Explain. B. Draw a diagram and label the directions of currents, and all other relevant quantities and vectors. C. Find the distance above the Large Wire the small thin wire will hover (net force of zero). D. Would your answers to parts A and C change if we wanted to find a distance below (rather than above) the Large Wire that the smaller thin wire could hover, due to their magnetic fields. Explain. Don't calculate any values but draw a new diagram and explain how this situation compares to the problem above.
