Magnetic Field Produced in each Coil

In this photo you see the set up we used to determine how the number of coils in a solenoid affect the magnetic field. Determining the magnetic field produced per coil with a constant current we were able to determine the length of the wire.

Here is chart of the number of loops N, current I, and Magnetic field produced B(loop). For every trial we found that the number of (B(loop)/(NI)) is similar for loops greater then 1. 

We used the these values to determine the length of the coils as 0.116m which is very large and can be attributed to in accuracy of the magnetic field sensors. 

Magnetic Field Characteristics

Using a solenoid and a magnet a voltage was produced without a power supply. A relationship was determined between the produced magnetic field from solenoid and displacement of the magnet, number of coils, and velocity.

We found that the magnetic field is proportional to the displacement of the magnet, velocity, and number of coils.
