Induced Current Apparatus
Product Code : SCL-PLE-11682
Quick Answer: The Induced Current Apparatus is a primary and secondary coil set: a low-resistance primary that fits inside a many-turn secondary, with a removable soft iron core and 4 mm safety sockets, for studying mutual induction.
Last updated: 18 October 2026
Key Features
- Primary coil of low-resistance insulated copper wire on a hollow former.
- Secondary coil with many turns of fine insulated copper wire.
- Nested design: the primary slides inside the secondary.
- Removable soft iron rod to strengthen the magnetic linkage.
- 4 mm shrouded safety sockets on both coils.
Technical Specifications
| Specification | Value |
|---|---|
| Primary coil | Low-resistance insulated copper winding on hollow former |
| Secondary coil | High-turn, fine-gauge insulated copper winding |
| Arrangement | Nested solenoids, primary inside secondary |
| Core | Removable soft iron rod |
| Terminals | 4 mm shrouded safety sockets |
How It Is Used
The primary is connected to a supply and the secondary to a sensitive meter. Switching the primary current on or off, or sliding the primary in and out, changes the flux through the secondary and induces a current in it. Repeating with the iron rod in place shows a larger effect, illustrating Faraday’s and Lenz’s laws.
Frequently Asked Questions
What is the soft iron rod for in the Induced Current Apparatus?
Placed inside the coils, the removable soft iron rod increases the magnetic linkage between primary and secondary, giving a larger induced current.
Why is a current induced in the secondary of the Induced Current Apparatus?
Changing the current in the primary changes the magnetic flux through the secondary, and that change induces a current in the secondary circuit.
