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 is shown by the x$\text{'}$s in Fig. $2.$ Select true or false for the current in the loop. $($The compass directions are defined in the usual way.$)$

fig

$$ fig$1$: Magnet moving West, induced current $\text{'}$a$\text{'}.$

$q,$ fig$1$: Magnet moving East, induced current $\text{'}a\text{'}.$

fig$2$: Loop moving South, no induced current.

False t

fig$2$: Loop moving North, induced current $\text{'}$b$\text{'}.$

$q,$ fig$1$: Loop moving West, induced current $\text{'}$a$\text{'}.$

$q,$ fig$2$: Loop moving East, induced current $\text{'}$b$\text{'}.$

The induced current tends to oppose any change in PHI of the coil.
