3) change in magnetic flux = Area*number of turns* change in magnetic flux
= pi*0.3^2 *(0.6 - 0)
= 0.17 Wb
Emf = rate of change of magnetic flux
= Nd
/ dt
= 10*0.17 / 0.7
= 2.4 V
so the first option 2.4V is the correct answer

A square loop of wire with a small resistance is moved with
constant speed from a field free region into a region of uniform B
field (B is constant in time) and then back into a field free
region to the left. The self inductance of the loop is
negligible.
When entering the field the coil experiences a magnetic force to
the left.
When leaving the field the coil experiences a magnetic force to the
right.

A magnetic field passes through a stationary wire loop, and its magnitude changes in time according to the graph in the drawing. The direction of the field remains constant, however. There are three equal time intervals indicated in the graph: 0 - 3.0 s, 3.0 - 6.0 s, and 6.0 - 9.0 s. The loop consists of 43 turns of wire and has an area of 0.13 m2. The magnetic field is oriented...
