Calculate the magnitude of the magnetic field at a point 25.0 cm from a long, thin conductor carrying a current of 2.00 A. 2. (a) A conducting loop in the shape of a square of edge length, ℓ = 0.400 m carries a current I = 10.0 A as shown in Figure P30.5. (a) Calculate the magnitude and direction of the magnetic field at the center of the square. (b) What If? If this conductor is reshaped to form a circular loop and carries the same current, what is the value of the magnetic field at the center?

3. An infinitely long wire carrying a current I is bent at a right angle as shown in Figure P30.6. Determine the magnetic field at point P, located a distance x from the corner of the wire. 4. A conductor consists of a circular loop of radius R= 15.0 cm and two long, straight sections as shown in Figure P30.7. The wire lies in the plane of the paper and carries a current I = 1.00 A. Find the magnetic field at the center of the loop.

Ch-30 Problems and Solutions Page 3 5. In Figure P30.23, the current in the long, straight wire is I 1 = 5.00 A and the wire lies in the plane of the rectangular loop, which carries a current I 2 = 10.0 A. The dimensions in the figure are c = 0.100 m, a = 0.150 m, and , ℓ= 0.450 m. Find the magnitude and direction of the net force exerted on the loop by the magnetic field created by the wire.

Ch-30 Problems and Solutions Page 4 6. Four long, parallel conductors carry equal currents of I =5.00 A. Figure P30.32 is an end view of the conductors. The current direction is into the page at points A and B and out of the page at points C and D. Calculate (a) the magnitude and (b) the direction of the magnetic field at point P, located at the center of the square of edge length , ℓ = 0.200 m.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
