A square loop is pushed into a narrow region of magnetic field of strength B = 0

Question

A square loop is pushed into a narrow region of magnetic field of strength B = 0.20 T at a speed of nu = 50 m/s. The resistance of the loop is R = 0.10 Ohm. The three drawings below show the following: A) The loop entering the magnetic field B) the loop moving after it has fully entered the field C) The loop leaving the field. A) What is the magnitude and direction of the induced current in the loop when it is entering the magnetic field? Clearly show your work and explain. B) What is the magnitude and direction of the induced current in the loop after it has fully entered the magnetic field? Clearly show your work and explain.

Explanation / Answer

while entering the field , acted upon by consatnt speed

ut this acts as open loop so that no emf and curruent is induce d

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

part B:

onnce it is fully immersed

emf e = lv B

emf e = 0.05 * 50 * 0.2

emf e = 0.5 volts

so induced current i = emf/R

i = 0.5/0.2 = 2.5 Amps

------

direction is CCW
