Awhina is constructing an electromagnet to demonstrate at the upcoming science fair. She is using wire, a nail, and a battery. Awhina also wants to make a chart to show which direction the magnetic field is flowing for each of her electromagnets. Describe how she would determine the direction of the magnetic field for the electromagnets. Include a description of how the magnetic field appears around the looped wire.

The magnetic is stronger when it is closer to the wires. the magnets rotates around the wire. she can determine the directions by telling if it is repelling or attracting objects that contain iron.

to determine the unit cost your would divide the total cost by the number sold.

7 bagels for $4.41       $4.41/7 = $.63 each at fresh side

5 bagels for $3.60         $3.60/5 = $.72 each at value mart
