Magnetic Demagnetising Coil
Product Code : JC-SL-4642
The magnetic demagnetising coil (SKU JC-SL-4642) is a solenoid wound with insulated copper wire and fixed on a base, complete with a switch and 4 mm socket terminals. It works on a low-voltage supply and is used to magnetise or demagnetise ordinary magnets, iron bars and strips in school electromagnetism practicals.
Specifications
The coil construction, fittings and supply requirements given in the listing are these:
| Product | Magnetic Demagnetising Coil |
| SKU | JC-SL-4642 |
| Coil | Solenoid wound with insulated copper wire |
| Mounting | Fixed on a base |
| Controls | Switch |
| Terminals | 4 mm socket terminals |
| Supply | Low voltage |
| Magnetising | A.C. or D.C. supply |

Uses of the demagnetising coil
- Magnetising iron bars and strips placed inside the solenoid
- Restoring or removing the magnetism of ordinary magnets
- Showing that a current-carrying coil produces a magnetic field
Scope of supply and ordering
The coil comes as described, on its base with the switch and sockets; the low-voltage supply is a separate item. Quantities and packing are agreed in the quotation.
Frequently asked questions
Can the coil demagnetise on a DC supply?
No. Magnetising works on A.C. or D.C., but demagnetising is done on A.C. only.
How is the supply connected?
Through the 4 mm socket terminals on the base, and the switch turns the coil on and off.
