| In this experiment a galvanometer is attached to a coil to assist in measuring the induction. The voltage is induced when a magnet it run through the coil at different speeds. This shows the relationship between a magnetic field, the change in the position oof the magnet and the current in the wire. |
There is a wire wrapped around this tube in order to measure the effects of different numbers of coil and the effects on current and magnetic field.
this is the measurements of the inductance and then magnetic field as the number of coils increases.
using these values we can calculate the elength of the wire. Science is a magical and disturbing beast.
