1. The stack of magnets works as one big bar magnet. Do the poles change when you divide the magnet into pieces? 2. In step 3 of the experiment, do both sides of the magnet attract the metal surface? Explain how a single magnet can repel the rest of the stack, but still stick to the other surface. 3. How does the magnet attract something that is originally non?magnetic? 1. Describe the direction of the compass needle as you moved...

5) Hold a magnaprobe above the magnet and follow the lines of magnetism around from one pole to another. Observe the compass dial as you move along the line of magnetism. What is the shape of the magnetic field above the magnet? 6) Place the north end of a bar magnet distanced from the south end of another bar magnet. (as shown below) Place a piece of plastic over the two magnets and sprinkle iron filings in the region between...
What is the direction of the induced magnetic field in the coil when the bar magnet is moving...
A coil is suspended around an axis which is colinear with the axis of a bar magnet.The coil is connected to a resistor with ends labeled “a” and “b”. The bar magnet moves from left to right with North and South poles labeled as in the figure. UseLenz’s law to answer the following question concerning the direction of induced currents and magnetic fields.What is the direction of the induced magnetic field in the coil when the bar magnet ismoving from...

III. Mapping the Field Around a Bar Magnet: An Observation Experiment Purposes: Design an experiment to take appropriate data to find a relationship. Construct a mathematical model to describe that relationship Description: Your task is to use a compass to map the magnetic field of a small magnet. Construct a circle of radius 10 cm on a clean sheet of paper, and mark points on the circle every 30°. Place the bar magnet so that its center is resting at...
