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...

Magnetic induction lab: 5 questions
A vertical bar magnet is dropped through the center of a horizontal loop of wire, with its south pole leading. At the moment just before the south pole passes through the loop, what is the direction of the induced current in the loop (viewed from above)? 2. Explain your answer to the previous question. 3.

Two bar magnets are arranged so that they are parallel to each
other. In case 1, north poles face each other on the right side. In
case2, south poles face each other on the right side. In what way
is the resulting field pattern the same, and in what way is it
different?
2-A bar magnet is placed on a flat surface so that the north
pole is on the left side and the south pole on the right. At...

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...

1) Describe the field. What is the most unique characteristic of the field? 2) Draw a simplified version of the field pattern that emerged when the iron filings were placed on the bar magnet. Be sure to show the shape of the field. Place your compasses in your magnetic field in the spots illustrated below. Does your compass needle line up with the flux lines? Draw an...

General Physics 2 w/o calc
Now suppose that the battery is removed and replaced with an ammeter. No current will flow through the wire because there is no energy source. Consider what will happen when a barmagnet is pushed toward the coil as shown in the figure below. When the coil "feels" the changing magnetic field caused by the approach of the bar magnet, it will thereby become energized; a current will begin to flow through it, and the ammeter will register that current. This...
