The strength of an electromagnet depends on several factors, including the number of loops (or coils) of wire around the core, the amount of current flowing through the wire, and the material of the core. In general, increasing the number of loops will increase the strength of the electromagnet.
Among the options provided:
- 10 loops
- 200 loops
- 5 loops
- 15 loops
The one with the **fewest loops** will produce the weakest magnetic field. Therefore, a **battery with 5 loops around the core will have the weakest force**.
