Technical Specifications
| Specification | Value |
|---|---|
| Coils | 3 enamelled copper wire coils |
| Turns | 5, 10, 20 |
| Base | Polished wooden base with Bakelite support ring |
| Coil orientation | Vertical |
| Terminals | At the base edge |
| Field mapping | Flat surface for iron filings or compass |
How It Is Used
Connect a coil through the terminals at the base edge, sprinkle iron filings on the flat surface or set a compass on it, and observe the field pattern. Switching between the 5, 10 and 20 turn coils, or changing the current, shows how field strength depends on current and the number of turns.
Frequently Asked Questions
How many turns do the coils on the Magnetic Field Apparatus have?
There are three coils of 5, 10 and 20 turns, so the effect of the number of turns on field strength can be compared.
