Question
Students in science class worked in groups to design and build a simple electric motor, like the one shown below.
All the motors were made using a battery, wire, and a magnet. However, each group altered either the type of wire, size of the magnet, or voltage of the battery to try to create the fastest spinning motor. The table below describes each group's design and how fast their motor spun.
Group 1 Group 2 Group 3 Group 4 Group 5
Wire Type insulated insulated copper copper copper
Battery Voltage 1.5 V 3.0 V 1.5 V 1.5 V 3.0 V
Magnet Size small large small large small
Speed of the Motor no spin no spin slow fast medium

To determine which combination of wire, battery, and magnet might create the fastest spinning motor, we can analyze the results from the given groups:
1. **Group 1**:
- Wire Type: Insulated
- Battery Voltage: 1.5 V
- Magnet Size: Small
- Speed: No spin
2. **Group 2**:
- Wire Type: Insulated
- Battery Voltage: 3.0 V
- Magnet Size: Large
- Speed: No spin
3. **Group 3**:
- Wire Type: Copper
- Battery Voltage: 1.5 V
- Magnet Size: Small
- Speed: Slow
4. **Group 4**:
- Wire Type: Copper
- Battery Voltage: 1.5 V
- Magnet Size: Large
- Speed: Fast
5. **Group 5**:
- Wire Type: Copper
- Battery Voltage: 3.0 V
- Magnet Size: Small
- Speed: Medium
From these results:
- **Wire Type**: Copper wire appears to be more effective than insulated wire since two of the three groups using copper spun their motors.
- **Battery Voltage**: Increasing the voltage seems to contribute to increased speed—Group 4 (1.5 V, copper, large magnet) spun fast, while Group 5 (3.0 V, copper, small magnet) spun at medium speed. Notably, the 3.0 V battery didn't help Group 2 either, suggesting that other factors (like magnet size and wire type) were at play.
- **Magnet Size**: The large magnet used by Group 2 and Group 4 likely helped the spinning speed, especially because Group 4 used a copper wire and still achieved a fast spin.
Based on this analysis, the most effective combination likely includes:
- **Copper Wire**: Effective and advantageous over insulated wire.
- **3.0 V Battery**: Higher voltage is likely to produce more speed.
- **Large Magnet**: Previous results indicate that a large magnet contributes positively to speed.
Thus, the optimal choice from the options provided would be:
**A. copper wire, 3.0 V battery, and a large magnet**.
