Experiment 6: The Magnetic Field in a Coil
Introduction: The goal of this experiment is to understand and observe the
relationships between magnetic field and current in a coil and magnetic field and number
of turns in a coil. To do this we must understan

1. A 1cm long horse fly hovers 1cm from a shiny sphere with a radius of 25cm. Describe the location of
the image of the fly, its type (real or virtual), and its length.

Experiment 2: Mapping the Electric Potential to Find the Electric
field
Introduction: The goal of this experiment was to examine and to map the space around various
electric charge distributions provided for us. This was done to give us a better understan
Experiment 5: series and parallel
Introduction:
The objective in this experiment was to study series and parallel circuits. We observed
current, resistance, and voltage in both circuits. We used ohms law (V=IR) to calculate
the current in a series circuit
Experiment 3: Measuring Capacitance
Introduction:
The goal of this experiment is to use a parallel plate capacitor to examine and
understand the circumstances that determine capacitance. To do this one needs to
understand the formula used calculate the ca
Experiment 4: Ohms Law
Introduction:
The goal of this experiment was to obtain a deeper understanding of the
relationship between current, voltage and resistance using Ohms Law (V = IR). In order
to explore Ohms Law and the mathematical relationship betwe
