Tangent Galvanometer
Pre-Lab
1. Why are you attempting to align the coils of the tangent galvanometer to the
Earth’s magnetic field?
2. Sketch the shape of the Earth’s magnetic field around the Earth. Why does the
Earth’s magnetic field at 38° latitude have a vertical component?
3. What is the magnetic field at the center of your tangent galvanometer if the 27
coils have a diameter of 35 cm and you are applying 2.56 amps of current?
4. What would be the ideal conditions for producing magnetic field in a coil?
