Concept

Problem: Click on the button with two coils in it in the lower part of the window. The circuit should now have two sets of coils. Place the bar magnet inside the coil containing two loops. Try to find a location where the stationary magnet induces a current in the coil and causes the light bulb to shine. Which of the following is correct? a) The light bulb shines due to an induced current if the magnet is inside the coil.b) The light bulb shines due to an induced current if one pole of the magnet is near the middle of the cell.c) There is no induced current in the coil, so the light bulb does not shine, if the magnet is stationary (for any location of the magnet). 

FREE Expert Solution

The stationary magnet has a magnetic field that does not change with time. Thus, there is no current induced on the coil.
