A rectangular wire loop of height h, width w, and net electrical resistance R lies in the x-y plane. As shown in the figure below, the entire region x < 0 of space is occupied by a constant, uniform magnetic field which points in the –z direction (into the page). In order to determine the magnitude of this field, a student pulls the wire loop out of the magnetic field region at a constant velocity v in the +x-direction, and measures the current I induced in the loop during this process. I = 17 μAR = 35 ohmsh = 3 cm w = 8 cmv = 2 cm/sec a) What is the direction of the current induced in the wire loop? b)What is the magnitude B of the magnetic field?

As shown in the figure below, a circular ring with a radius of a is folded along a line across the diameter so that the two semicircles are perpendicular. In the magnetic field, this ring was rotated at a constant angular velocity over time, as shown in the figure. The axis of rotation is an extension of the fold-off line and is perpendicular to the magnetic field. The resistance of the ring is R. (1) Give a qualitative explanation of what will happen. (2)Find the current flowing through the ring. (3)What torque should be applied to the ring to allow it to rotate at a constant angular speed? (4)What do you have to do to turn it N round? (5) What energy changes from ring to heat? (6) How much energy changes from ring to heat? * I'll be so thankful and satisfied to get answer just least 3 of 6 questions..

A bar magnet is attached solidly to a frictionless surface and its length is aligned with the x axis. To the right of the first magnet a short distance away is a second bar magnet with its center placed on the x axis and its length perpendicular to the x axis. The second magnet is free to move. Once placed in position at rest, which best describes the initial motion of the second magnet? O The magnet will move away from the fixed magnet. The magnet will not move. The magnet will start to rotate. O The magnet will move toward the fixed magnet.
Two parallel long (infinite for our purposes) wires are oriented along the z-axis. The figure below shows the (xy)-plane perpendicular to the wires, including the positions where the wires cross this plane. The wires carry some unknown electric currents I₁ and I₂, which you need to find from a single measurement of the magnetic field B=B₂ i + By J at point A, whose position in the plane is also indicated. We will treat the currents algebraically: the current I is positive when it runs in the direction of the z-axis and negative when it runs in the opposite direction. In the right-hand system of coordinates, the z-axis is directed out of the screen towards us. The geometric parameters are known: a=0.52 cm, b=0.34 cm. 1₁ a a 1₂ Given the measurement of the magnetic field: By=-0.52 G and By=-0.48 G, what is the unknown current I₁?: 4₁= What is the unknown current I₂?:
