Magnetic Field Along the Axis of a Coil

A current carrying coil produces a magnetic field along its axis which is defined by Biot Savart’s law.
In the present setup, the study of magnetic field along the axis is investigated with coils having different dimensions and turns. The magnetic field is measured using a axial hall probe and digital gaussmeter.

Features

• DC Regulated power supply with safety sockets and dual temperature controlled exhaust fan.
• Digital Gauss meter with least count of 0.1 Gauss.
• 6 coils with different turns and 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 Biot-Savart’s law
• To study the magnetic field along the axis of a current carrying multi-turn coil.
• To study the dependency of magnetic field on coil diameter and number of turns
