Answer 1

To determine the strength of the electromagnets, we can consider both the current intensity and the number of turns in the coil. Generally, the strength of an electromagnet can be assessed by the following factors:

1. Current Intensity: Higher current leads to a stronger magnetic field.
2. Number of Turns: More turns in the coil also contribute to a stronger magnetic field.

Here's the information provided in the table:

• Electromagnet P: Medium Current, 20 Turns
• Electromagnet Q: Low Current, 20 Turns
• Electromagnet R: Low Current, 15 Turns

Now we can evaluate:

1. Electromagnet P has medium current, which generally implies a stronger magnetic force than any low current.
2. Electromagnet Q and R both have low current, but Q has more turns (20) compared to R (15).

Given that P has medium current, it will be stronger than both Q and R. Between Q and R, since Q has more turns, it would be stronger than R.

Thus the order from strongest to weakest magnetic force is:

P, Q, R.

The correct response is: P, Q, R.
