The flexible loop in the figure below has a radius of 14 cm and is in a magnetic field of strength 0.12 T. The loop is grasped at points A and B and stretched until its area is nearly zero. If it takes 0.21 s to close the loop, what is the magnitude of the average induced emf in it during this time? |ε| = mV

A flexible circular loop 10 cm in diameter lies in a magnetic field with magnitude 2.00 T, directed into the plane of the page as shown on the figure below. The loop is pulled at the points indicated by the arrows, forming a loop of zero area in 0.250 s. a) Find the average induced emf in the circuit. b) What is the direction of the current in R : from a to b or from b to a ? Explain your reasoning. c) Does the operator who pulls on the circuit experience some resisting force? If yes, what is its origin (only a qualitative answer is needed)? Hint: To determine the average emf, remember the difference between the instantaneous speed v = dx dt and the average speed vav = Δx Δt. The same works for the emf.

A circular conducting loop with radius 2.10 cm is placed in a uniform magnetic field of 0.850 T with the plane of the coil perpendicular to the magnetic field as shown. The magnetic field decreases to 0.250 T in a time interval of 30.0 ms. What is the average induced emf in the loop during this interval? mV

An arbitrarily curved wire that carries a current between two endpoints in the presence of a uniform magnetic field will experience the same net magnetic force as a straight wire carrying the same current between the same endpoints. Essentially, any forces experienced by parts of the wire that curve or twist away from the straight-line path are canceled out by forces on sections that curve back toward the original path. Furthermore, if the wire forms a closed loop in between the endpoints, the net force on the closed loop is zero. Using this result, consider a town where the Earth's magnetic field has a magnitude of 51.3 μT. The magnetic field vector lies in a vertical plane defined by the north-south and up-down axes, and it points 60.0∘ below the northward direction. In this town, a storefront window lies along the north-south vertical plane, and in the window is a neon sign (which is a thin current-carrying discharge tube). The sign carries a 35.1 mA current, starting from the lower south corner of the window, and ending at the opposite corner, which is 1.32 m to the north and 0.850 m upward. The sign spells out the word "BURGERS" between the two points. What is the net vector magnetic force (in μN ) on the neon sign? (Take east to be the +x-axis, up to be the +y-axis, and south to be the +z-axis. Do not include units in your answer.) F→B = μN
