Question

2. A lon& straight wine carries a current in the +# direction, as shown. Above and below the wire are two conducting loops, rectangular and elliptical. (a) The current is steadily increased. What is the dircection (CW or CCW) of the induced current in each of loops? Explain. (b) The current is held constant while each conducting loop is pulled away from the wire with constant speed (the rectangular loop is pulled up and the elliptical loop is pulled down). What is the direction (CW or CCW) of the induced current in each of the loops? Explain.

Explanation / Answer

from lenz law, indued current appears in a coil aways in a driection opposite to the motion of its cause

part A :

for right Current, magnetic field will be out the paper

so increasing current will make increasing magnetic field into the papar

so Current in the top loop will be away i.e CCW

--------------------

in the bottom loop, magentic field will be into induced current will be CCW.

-------------------------------------

when top loop is pulled away Induced current will be CW

and for Bottom loop also induced current will be CW
