Question

3 imagine that you want to collect extra nails and screws from a construction site. to do this, you attach a magnet to the end of a stick. unfortunately, your tool doesnt pick up any of the nails or screws on the ground. what two changes could you make to improve it?
use a larger magnet
use a stronger magnet
hold the magnet closer to the ground
hold the magnet farther from the ground

Explanation:

A stronger magnet has a more powerful magnetic field, enabling it to attract metal objects like nails and screws more effectively. Holding the magnet closer to the ground reduces the distance the magnetic field needs to act over, as magnetic force weakens with distance, so this makes it more likely to pick up the metal items. A larger magnet does not inherently mean a stronger magnetic field, and holding it farther away would only decrease the magnetic force's effectiveness.

Answer:

• Use a stronger magnet
• Hold the magnet closer to the ground
