Magnetic Field Demonstrator – Vertical Wire

The Magnetic Field Demonstrator – Vertical Wire is a compact electromagnetism apparatus designed for investigating the magnetic field generated around a straight current-carrying wire. Its vertical conductor arrangement makes the surrounding magnetic-field pattern convenient to observe using suitable field indicators.

The apparatus incorporates a vertical wire approximately 1.5 mm in diameter. Electrical terminals are provided to allow the conductor to be connected to a suitable controlled DC power source for experimental use.

When electric current flows through the vertical conductor, a magnetic field develops around the wire. The magnetic-field lines form approximately concentric circular paths around a long straight conductor, providing a clear demonstration of the relationship between electricity and magnetism.

Micro Technologies supplies the apparatus for operation at a maximum current of approximately 8 A. The applied current should remain within the specified limit to protect the conductor and electrical connections from excessive heating.

Suitable plotting compasses or other magnetic-field indicators can be positioned around the vertical wire to investigate the direction of the field. The orientation of the indicators changes according to their position relative to the conductor.

The apparatus can also be used to investigate the effect of reversing the direction of current. When current direction is reversed, the direction of the magnetic field surrounding the wire also reverses.

With suitable external measuring equipment, different current values can be applied within the rated range to compare the resulting magnetic effects. This allows the relationship between conductor current and magnetic-field strength to be investigated.

Its straightforward vertical-wire arrangement, accessible terminals, and compact construction make the apparatus useful for repeated experiments involving current-produced magnetic fields and electromagnetism.

FAQs

What is the Magnetic Field Demonstrator – Vertical Wire used for?

It is used to investigate the magnetic field produced around a straight wire when electric current flows through it.

What is the diameter of the vertical wire?

The wire has an approximate diameter of 1.5 mm.

What is the maximum current rating?

The maximum current is approximately 8 A.

What shape is the magnetic field around the vertical wire?

For a long straight current-carrying conductor, the magnetic-field lines form approximately concentric circles around the wire.

Can the direction of the magnetic field be investigated?

Yes. Suitable plotting compasses can be positioned around the conductor to observe the direction of the magnetic field.

What happens if the current direction is reversed?

Reversing the current reverses the direction of the magnetic field surrounding the conductor.
