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...

4. (3 pts.) Suppose that you create a simple electromagnet at home by evenly wrapping a thin copper wire 550 times around an 8.0-cm-long iron rod. You then connect the wire to a battery that passes 250 mA through the wire. The iron rod has a radius of 6.0 mm and a magnetic permeability le-150μο. Assuming that this forms an "ideal" solenoid, find the strength of the magnetic field generated inside (and near the ends of) the electromagnet.

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...

elaborate on this quote. Does this mean that if I place a
compass above the wire, the NORTH end of the compass will point
towards the wire? like this?
If so, can we imagine the wire as being the virtual magnet,
where the "top" of the wire simulates a north pole and the "bottom"
of the wire simulates a south pole? Why would this be? Is it
because the field lines go from the north end of the magnet to...

Visitor from Con Ed from a galaxy far away have placed a large (black) ring of wire in the arctic circle around the geographic north pole of the earth. Now they are reducing the earth's magnetic field (but not changing its sign) to induce electric current in their large ring of wire. As seen from far above the north pole of the earth, is their current flowing CLOCKWISE or COUNTER-CLOCKWISE?
