Biot Savart’s Law
A current carrying circular conductor loop produces a magnetic field along its axis which is defined by Biot Savart’s law.
B = μο / 2 x I . R2 / (R2+x2)3/2
Where R=Radii of the loop, x =Distance from axis through center.
In present setup, three conductor loops of different radii mounted on a special loop holder is provided for investigation. The magnetic field is measured using axial hall probe. A high current power supply is provided to produce the magnetic field.
Features:
- DC Regulated power supply with safety sockets and dual temperature controlled exhaust fan.
- Digital Gauss meter with least count of 0.1 Gauss.
- 3 coils with different diameter.
- 4mm Safety sockets and plugs are used to make connection.
- Specially designed hexagonal optical bench with locking arrangement for precise positioning.
Objectives:
- To study the magnetic field of a circular conductor as a function of the current.
- To study the magnetic field of a circular conductor as a function of distance along the axis of the conductor
- To study the magnetic field as a function of loop radius.
