Question

Back to Mail 1:12 PM loncapa2.fsu.edu 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. out of Fig. 1 Fig. 2 True Fig 2: Loop moving South, no induced current Falsi: Loop False Fig 2: Loop moving North, induced current 'b FalseFig 1: Magnet moving East, induced current 'a'. TrueFig 1: Magnet moving West, induced current 'a Tue Fig 1: Loop moving West, ind True Fig 1: Loop moving West, induced current True Fig 2: Loop moving West, induced current G ) Incorrect. Tries 2/10 Submit Answer ous

Explanation / Answer

(1) If loop in 2 figure moving south then magnetic field is not increasing so NO induced current

True

(2) If it is moving north then no magnetic field is changing so no induced current

False

(3) In fig 1 magnet moving East so in loop current will induce such that its right face become north pole to oppose the motion. hence current will induce b

False

(4) for moving west induced current will be towards a so this is correct

True

(5) Loop is moving west so to oppose it current should be along b

False

(6) Loop moving west in fig 2 so induced current should be along b

False
