Hi, I can't work out this question, any help is appreciated thanks!

Thanks again!

The figures below show two different situations where a current may be induced in a loop by Faraday's Law, with the direction determined by Lenz Law. The magnetic field is shown by the sin Fig. 2. Choose true or false for each statement for the current in the loop. The compass directions are defined in the usual way) ON SO fig 1 x a X X X X X X X X X X X fig 2. X X fig2: Loop moving North, induced current b. fig2: Loop moving North, no induced current. fig2: Loop moving South, induced current b fig1: Magnet moving East, induced current b fig1: Loop moving East, induced current a fig2: Loop moving South, induced current a

Explanation / Answer

a) False, since the flux is not changing through the loop, there is no induced current.

b) true

c) false

d) false, if the magnet is moving east, less flux will travel through the loop.Thus, the induced current will be such as to gain flux. Using the right hand rule,more flux will be in the loop if current travels in the direction indicated by ’a’.

e) true

f) false
