Deflection Magnetometer Manufacturer,Supplier and Exporter in India
Product Code : EL-PL-13408
Jlab Export is a leading Deflection Magnetometer Manufacturer,and suppliers in India
Deflection Magnetometer (code EL-PL-13408) is a removable compass box set on a polished base of non-warping wood, with a metre scale running along the base so that the distance from a magnet to the needle can be read directly. Physics classes use it to compare magnets and to study the strength and direction of a field at a point. JLab manufactures the magnetometer in Ambala, India, as model JL305.

Setting Up the Tan A and Tan B Positions
In the Tan A (end-on) position the base points magnetic east–west, the needle rests north–south, and the magnet lies along the base with its axis pointing at the needle. In the Tan B (broadside-on) position the base points north–south and the magnet lies across it with its axis east–west. Either way the magnet’s field at the needle is at right angles to the Earth’s horizontal field, so the tangent of the deflection gives the ratio of the two fields.
What Students Measure
Two bar magnets placed in turn at the same distance can be compared by the tangents of their deflections, which gives the ratio of their magnetic moments. Readings at several distances show how quickly a magnet’s field weakens as it moves away. Reading both ends of the needle, reversing the magnet end for end and repeating on the other side of the box averages out an off-centre pivot or an unevenly magnetised bar.
