Question

The Figures below show two different situations where a current may be induced in a loop according to Faraday's Law, with the direction given by Lenz' Law. The magnetic field strength in Figure 2 is represented by the density of dots. Select true or false for the current in the loop. The cardinal directions are as defined in the compass rose.

Induced Current The figures below show two different situations where a current may be induced in a loop according to Faraday's Law, with the direction given by Lenz' Law. The magnetic field strength in Figure 2 is represented by the density of dots. Select true or false for the current in the loop. The cardinal directions are as defined in the compass rose. B-field points out of page SE Fig. 1 Fig. 2 False Fig 1: Magnet moving East, induced current 'b'. True True Fig 1: Loop moving West, induced current a Fig 1: Loop moving West, induced current'a'. False Fig 2: Loop moving West, no induced current. True Fig 2: Loop moving East, induced current 'a' True Fig 1: Magnet moving West, induced current 'a'. True Fig 2: Loop moving South, induced current 'b'. Submit Answer Incorrect. Tries 3/10 Previous Tries

Explanation / Answer

this problem only have two goals

1) the right hand rule

2) lenz law

by the right hand rule current direction is -a- for two figures in any case. The lenz law flip this current direction by the minus sign, so the current direction for both figures is -b- all the way, therefore the answers will be:

True ( the current is always b directed)

False (the current is always b directed)

False (always that exist movement a current b directed is induced)

False ( the current is always b directed)

False ( the current is always b directed)

False (no current induced too 'cause in this region not exist magnetic field)
