Magnetic Field of a Solenoid Purpose: To determine the winding density of an air-core solenoid. Theory: B nI 0 Equipment: air-core solenoid, a current probe (or voltage probe), and a magnetic field Students are told to determine n graphically. They can also be told to determine the number of layers of windings. To do this, they must estimate the number of wrappings per unit length, which is pretty hard to do!
