Tangent Galvanometer

The Tangent Galvanometer is a practical magnetism apparatus designed for investigating the relationship between electric current and the magnetic field produced by a current-carrying coil.

The instrument incorporates a circular coil wound on a non-magnetic supporting stand. The coil has a diameter of approximately 35 cm, providing a well-defined experimental arrangement for studying the magnetic field generated by current flowing through the winding.

A 46 mm magnetic compass is positioned in relation to the coil. When current flows through the coil, the resulting magnetic field interacts with the horizontal component of the Earth’s magnetic field and causes the compass needle to deflect.

The observed angular deflection can be used to investigate the relationship between electric current, magnetic-field strength, and compass orientation.

Micro Technologies provides 4 mm electrical sockets for convenient connection of the coil to a suitable controlled electrical supply.

The apparatus can also be used to investigate the magnitude and direction of the horizontal component of the Earth’s magnetic field when used with appropriate experimental procedures and measuring instruments.

The Tangent Galvanometer is based on the tangent-law relationship, in which two mutually perpendicular magnetic fields produce a resultant field whose direction can be determined from the compass deflection.

Its large circular coil, non-magnetic construction, integrated compass, and convenient electrical terminals make the apparatus suitable for quantitative and qualitative magnetism investigations.

A user manual is supplied with the standard apparatus to assist with setup and experimental operation.

FAQs

What is a Tangent Galvanometer used for?

A Tangent Galvanometer is used to investigate the magnitude and direction of the magnetic field produced by an electric current and can also be used to study the horizontal component of the Earth’s magnetic field.

What is the diameter of the coil?

The coil has an approximate diameter of 35 cm.

What type of stand is used?

The coil is wound on a non-magnetic stand to minimize interference with magnetic-field measurements.

What size compass is provided?

The apparatus includes a magnetic compass approximately 46 mm in diameter.

What electrical connections are provided?

The apparatus is equipped with 4 mm sockets for connection to a suitable electrical circuit.

What happens when current flows through the coil?

The current produces a magnetic field that interacts with the Earth’s horizontal magnetic field, causing the compass needle to deflect.

What principle does a Tangent Galvanometer use?

It operates using the tangent law of magnetism, which relates the angular deflection of a magnetic needle to two perpendicular magnetic fields.

Can it be used to investigate the Earth’s magnetic field?

Yes. The apparatus can be used to investigate the magnitude and direction of the horizontal component of the Earth’s magnetic field.

Can current and magnetic-field strength be compared?

Yes. By measuring compass deflection under controlled conditions, the relationship between current and the magnetic field produced by the coil can be investigated.

Why is a non-magnetic stand important?

A non-magnetic stand helps reduce unwanted magnetic influence on the compass and experimental magnetic field.
