2. Most people need a compass to navigate using magnetic fields, but birds, whales, deer, and many other organisms have the ability to detect Earth's magnetic fields without a compass. The mechanism that many organisms use to detect the magnetic field is still not entirely understood. However, the mechanisms of a group of bacteria that align with the magnetic field of Earth are well understood. The bacteria provide scientists with a simple organism that they can study to find out how organisms can naturally detect magnetic fields. What would be a reasonable hypothesis about how these bacteria detect the magnetic field? A. The bacteria respond to electric fields. B. The bacteria have iron particles in their bodies. C. The bacteria can see magnetic fields. D. The bacteria can detect gravity.

What happens when you break a bar magnet in two? a.You get two separate poles. One piece will be the north pole, the other will be the south pole. b.You get two bar magnets. Each has a north and south pole. c. The poles discharge. The act of breaking the magnet allows the magnetic charge to move so as to cancel each other out the same way protons can cancel electrons with electric charge. d. You cannot have a magnet without two poles, so the pieces will no longer be magnetic.
3. DETAILS MY NOTES You are working during the summer at a company that builds theme parks. The company is designing an electromagnetic propulsion system for a new roller coaster. A model of a substructure of the device appears in the figure below. The rod is of length d = 1.00 m and mass m = 0.700 kg. The rod carries a current I = 100 A in the direction shown and rolls along the rails of length L = 15.0 m without slipping. The entire system of rod and rails is immersed in a uniform downward-directed magnetic field with magnitude 8 = 1.90 T. The electromagnetic force on the rod is parallel to the rails, causing the rod to roll to the right in the figure. When a full-scale device is produced, this rod will represent the axle of wheels on which the car and i on the grounds of the company. By projecting the rod from the rails in a horizontal direction from a height h = 1.80 m, the projection speed can be determined from how far from the ends of the rails the rod hits the ground. Your…
