BIOT-SAVART LAW

BIOT-SAVART LAW   This equipment has been designed for the verification of Biot
Savart law inside circular turns of different diameter, and inside
coils of different diameter, length and number of turns. In the
first case, the verification concerns the variation of magnetic
field versus the diameter of circular turn, the current intensity
and the distance from turn centre. In the second case, magnetic
field is calculated versus the number of turns of the coil, coil
radius, its position along coil axis, length of the same coil. The
equipment consists of a rail on which circular turns and coils
powered by a variable current power supply are positioned.
The magnetic field is measured with a magnetic field probe
connected to a teslameter. The magnetic field created by
the circular turns is measured with a magnetic field probe
horizontally positioned at the center of the turn, or at different
distances from the center of the turn, whereas the magnetic
field created by the coil is measured with an axial magnetic
field probe positioned along the axis of the coil itself. Thus
a precise detection of magnetic field versus position can be
carried out. Furthermore, the current applied to the turn or to
the coil can be assessed
