Materials for Lab 2 D-cell batteries battery-holder for 2 D-cell batteries 2 large paper clips 2 bar magnets 1 m insulated, heavy gauge copper wire dark-colored nail polish fine sandpaper or steel wool AA battery or other cylindrical item about 1.5 cm in diameter compass paper cup scissors marking pen masking tape needle-nose pliers (optional)

I used a different wire because the wire they wanted me to use did not come in my science kit. I made note of it in my observations and materials list.

Here is what the ends of my wore look like after I have stripped the coating off.

A look at my wire coil.

Step # 4: My paper clip cradle. The heavier your paper clips the better they work.

Step #5: Make sure when you place your paper clip in the battery holder it is touching the ends of the battery. You want electrons to flow through your paper clips.

Use your needle nose pliers to squeeze the ends of it together and keep your paper clip in place.

I had to make my wore coil smaller and the ends shorter to fir my paper clip cradle. Do not be afraid to make adjustments to your materials as you go. Just remember to include that in your observations.

When you make your compass Platform remember to have your wire coil parallel with your compass platform.

My bar magnets taped together. North with North and South with South.

Be very careful when you paint your wire. I got too much on and had to use the sand paper and my fingernail to remove it from the bottom.

My wire coil was not rigid enough, and was too heavy to make a complete turn. (Made those notes in observations). But I did see the wire coil respond when I placed my magnet near it. It responded differently when I used the North and the South end.
