Please explain so that we can understand your reasoning when you answer each of these. 'i. As illustrated, the permanent magnets establish a uniform field of (M tesla (T) that goes through the loop. What is the direction of the magnetic field at the loop from the permanent magnets? 2. The loop is free to rotate around a horizontal axis such that the contacts with the battery provide current into the loop, The positive voltage of the battery symbol on the right is the lower, longer, line. Thus, the lower connection is to the positive side of the battery, and the current flows into the lower side of the loop, then around and out the top to the negative side of the battery. When the loop rotates past the vertical, the contacts to the battery and the direction of the current in the loop revers.. imagine that the loop rotates about 45 degrees to raise the upper horizontal \\ re so that the plane of this loop is vertical, rather than slanted as we see it in the figure. Looking into the end of the loop as we see it here, the loop would be rotated about 45 degrees clockwise to put the ho izontal Wire at the top. When the loop plane is vertical, the CL 'ent flows through the contact, into the lower wi e, across and then up to the upper r. How do the forces on the 4 sides differ from one another? in what direction, if any, will it rotate as a consequence of the magnetic forces acting on it when plane of the loop is vertical? Please carefully explain your answer 3. Answer the same question with the loop horizontal in the figure. 4 The connection to the battery is through a \"commutato which provides the connection to the battery through a contact that changes as the coil rotates. What is the functional purpose of the split connection to the battery? 5. Suppose that the loop is square with sides 2 cm long sides, and that a current of 15 amperes flows through the circuit. How do forces on the y 'es combine to produce a torque that would rotate the loop? 6 If oriented to produce the maximum torque, what would be the force producing the torque on each of the 4 sides of the square? Give your answer in n 7 If you removed the battery and replaced it With a 10 ohm resistor, explain why you rid have to exert a force on the coil to rotate around one time
