Your niece wants to study the effects of uniform magnetic fields on ladybugs for her science fair project, but you forgot that she asked for your help until the last possible minute. Fortunately you realize you can make the perfect ladybug magnetic chamber for her using thespare 12 V car batterysalvaged from your recently deceased 1994 Dodge Omni, 40 ft of fine gauge insulated copper wire "borrowed" from your roommate’s speakers, a 3W light bulb likewise"borrowed" from your roommate’s flashlight, which is normally powered by four D batteries in series, and a recentlyemptied can of Mt. Dew. Sketch the design for your "magneto-ladybug" house, and calculate the highest possible uniform field you can obtain. What’s the light bulb for?
