“Magnetic Field of a Coil”
Experiment 2.5
I. Objectives:
To produce a strong magnetic field just by looping the wire into coils
II. Materials:
6 V or 9 V batteries
50 cm of bare 12- gauge copper wire
Stiff cardboard and scissors
Wooden dowel (about 15 cm long x 4 cm diameter)
Iron filings
2 plotting compasses
Connecting wires with alligator clips
III. Data/Observations/Results:
IV. Generalization/Conclusion:
A field coil is an electromagnet used to generate a magnetic field in an electro-magnetic machine, typically a rotating electrical machine such as a motor or generator. It consists of a coil of wire through which a current flows. A magnetic field is a mathematical description of the magnetic influence of electric currents and magnetic materials. The magnetic field at any given point is specified by both a direction and a magnitude (or strength); as such it is a vector field.
V. Questions:
1. Describe the direction, shape, and spacing of the magnetic field lines in the core of the coil.
The magnetic field lines for a straight conductor are concentric circles around the conductor. As the distance from the conductor increases, the field gets weaker and the lines become more widely spaced.
2. What happens to these magnetic field lines at the end of the coil?
At both ends of the coil and on both sides, the magnetic field is quite weak, as the field lines begin to bend and spread out.
3. Describe the magnetic field in the region to either side of coil.
The region in which magnetic forces act, the
