Select the Transformer tab, which contains an electromagnet at left (containing a DC battery) and a pickup coil attached to a light bulb at right. The electromagnet produces a magnetic field very similar to that of the bar magnet. Try to find a location where the stationary electromagnet (with a DC current) induces a current in the pickup coil and causes the light bulb to shine. Which of the following is correct?
1. There is no induced current in the coil, so the light bulb does not shine, if the electromagnet is stationary (for any location of the electromagnet)
2. The light bulb shines due to an induced current if one pole of the electromagnet is near the middle of the coil.
3. The light bulb shines due to an induced current if the electromagnet is inside the coil.
