Apparatus for the study of Biot-Savart's Law

Holmarc’s Apparatus Model No: HO-ED-EM-05 has been designed for the study of Biot - Savart’s law. This law can be applied practically to calculate the magnetic field produced by an arbitrary current distribution. It gives fundamental quantitative relationship between an electric current and the magnetic field it produces. The law is also valid for a current consisting of charges flowing through space.

The magnetic field along the axis of wire loops and coils of different dimensions is measured using a Gauss meter. The relationship between the maximum field strength and the dimension is investigated and a comparison is made between the measured and the theoretical effects of position. The Gauss meter probe is mounted on a rail with a scale. It can be moved smoothly and precisely for measurement of magnetic field along the center of the coils. In general, any current loop has a magnetic field and thus has a magnetic dipole moment. This helps to explain why some materials exhibit strong magnetic properties.

Experiment:

    To study the variation of magnetic field due to Helmholtz coil and single coil carrying current

    To determine the magnetic field constant

    To measure the magnetic flux density in the middle of various wire loops using the gauss meter
