Two powerlines, labeled line #1 and line #2, are positioned east to west as shown and are apart. The current in line #1 points east, and the current in line #2 points west. In between the powerlines is a rectangular conducting loop of total resistance 360 ohms and area.
What is the magnitude and direction of the magnetic force on 20 meters of current #1 due to current #2? If Fe1 is the force on current #1, what can we say about Fe2, the magnetic force on current #2? Identify which of the following is correct:
i. Fe2 and Fe1 are in the same direction
ii. Fe2 and Fe1 are in the opposite direction
iii. Fe2 and Fe1 are in the same direction
iv. Fe2 and Fe1 are in the opposite direction
v. Fe2 and Fe1 are in the same direction
vi. Fe2 and Fe1 are in the opposite direction
Timeline of events given below: At what time(s) is there an induced current in the rectangular loop? What is the magnitude and direction of the induced current(s)?
At time (t=0s), the loop begins to move east at 0.7 m/s. At t=15s, someone negligently flies a drone into line #1 and the current in line #1 begins to linearly decrease. At t=17s, the loop stops moving but remains in the middle of the powerlines. By t=23s, current #1 is down to 3A.
