Magnetising and Demagnetising Coil
Model Number: MTME-24
The Magnetising and Demagnetising Coil is designed for practical experiments involving the magnetisation and demagnetisation of ordinary magnets, iron bars, and strips. Micro Technologies supplies the apparatus with a 250 mm long solenoid wound with insulated copper wire, securely mounted on a base with a switch and 4 mm electrical terminals. The unit operates from 12 V AC or DC at up to 6 A, providing a convenient setup for investigating magnetisation, demagnetisation, solenoid fields, and electromagnetic effects.
Product Specification
The Magnetising and Demagnetising Coil is a practical laboratory apparatus designed for investigating the magnetisation and demagnetisation of magnetic and ferromagnetic materials. It provides a convenient solenoid arrangement through which suitable bars, strips, and magnets can be inserted for experimental treatment.
The main component of the apparatus is a 250 mm long solenoid wound with insulated copper wire. The coil is mounted securely on a stable base, providing convenient access to the hollow central region of the solenoid.
Ordinary magnets, iron bars, and suitable metal strips can be inserted through the center of the coil. When an appropriate electric current passes through the solenoid, a magnetic field is generated along its axis and can be used to magnetise suitable ferromagnetic specimens.
Micro Technologies provides the apparatus with an integrated switch and 4 mm electrical terminals, making connection to a compatible laboratory power source straightforward.
The apparatus is designed to operate from approximately 12 V AC or DC, with a maximum current of 6 A. The appropriate supply mode can be selected according to whether magnetisation or demagnetisation is being investigated and the experimental procedure being followed.
For magnetisation experiments, a suitable DC supply can produce a magnetic field with a consistent polarity through the solenoid. A ferromagnetic specimen placed inside the coil can become magnetised under suitable conditions.
For demagnetisation investigations, a suitable alternating magnetic field can be produced using an AC supply. When performed using an appropriate procedure, the changing magnetic field can progressively reduce the residual magnetisation of a specimen.
The apparatus also provides a practical way to investigate the magnetic field associated with a solenoid and the relationship between electrical current, coil excitation, and magnetic effects.
Its long coil, stable mounting, accessible terminals, and dual AC/DC operating capability make the Magnetising and Demagnetising Coil a versatile apparatus for repeated magnetism and electromagnetism experiments.
