Analyzing Magnetic Fields with Solenoids 1Running head: ANALYZING MAGNETIC FIELDS WITH SOLENOIDSAnalyzing Magnetic Fields with SolenoidsJames KennicuttPhysics 690Analyzing Magnetic Fields with Solenoids 2AbstractStudent difficulty understanding electricity and magnetism is a common problem in manyphysics courses. Constructing simple solenoids out of a D-Cell battery, copper wire, a nail, and a straw can help students understand this difficult topic. This experiment is designed to help students visualize magnetic fields created by moving electrons in a current carrying wire. Students also learn about the intensity of magnetic fields when an iron core is introduced into the solenoid.Analyzing Magnetic Fields with Solenoids 3Analyzing Magnetic Fields with Solenoids in Introductory PhysicsJames Kennicutt Dept. of Physics, SUNY-Buffalo State College, 1300 Elmwood Ave, Buffalo, NY 14222 <[email protected]>Abstract:Student difficulty understanding electricity and magnetism is a common problem in manyphysics courses.
