Roughly where is the magnet when the light bulb is the brightest? (the brightness of the light bulb correlates with how much the needle of the voltmeter gets deflected away from the middle.) now, let’s look at a situation with changing flux. starting from the far left of the screen, move the magnet to the right so it goes through the middle of the two loops coil at a constant speed and out to the right of the coil. roughly where is the magnet when the light bulb is the brightest? (the brightness of the light bulb correlates with how much the needle of the voltmeter gets deflected away from the middle.) the brightness of the light bulb is the same, regardless of the location of the magnet (as long as it is moving). the light bulb is brightest when the middle of the magnet is in the middle of the coil. the light bulb does not shine since the magnet is moving at a constant speed. the light bulb is brightest when either end of the magnet is in the middle of the coil

The electric field between square plates of a parallel-plate capacitor has magnitude e. the potential across the plates is maintained with constant voltage by a battery as they are pulled apart to twice their original separation, which is small compared to the dimensions of the plates. the magnitude of the electric field between the plates is now equal to a)e b)e/4 c)e/2 d)4e e)2e
