Product Code : SCL-PLE-11530
Quick Answer: The Magnetic Effect of Current is a demonstration apparatus showing that a current in a copper conductor produces a magnetic field around it. Run from a low-voltage DC source, the field is revealed with a compass or iron filings.
Last updated: 18 October 2026
Key Features
- Copper conductor on a plastic base with power terminals.
- Compass or magnetic indicators show the field around the wire.
- Demonstrates field direction and the right-hand thumb rule.
- Introduces the link between electricity and magnetism.
Technical Specifications
| Specification | Value |
|---|---|
| Conductor | Copper wire or coil |
| Base | Plastic |
| Components | Conductor, power terminals, compass or indicator setup |
| Power supply | Low-voltage DC source |
How It Is Used
Connect the conductor to a low-voltage DC supply and switch on. Students place the compass or sprinkle iron filings near the wire, note the deflection or pattern, and use the right-hand thumb rule to explain the direction of the field lines. Avoid leaving the current on for long, as the wire can overheat.
Frequently Asked Questions
How is the field seen on the Magnetic Effect of Current apparatus?
When current flows, a compass or iron filings placed near the conductor show the field; its direction can be worked out with the right-hand thumb rule.
What supply does the Magnetic Effect of Current apparatus need?
A low-voltage DC source connected to the power terminals.
