Kayla has two magnets. She would like to know how much magnetic energy is stored in each one. What would be the best way for her to determine which magnet has the most magnetic energy?
Responses

Attach wires to the ends of each magnet and measure the currents going through the wires.

Put each magnet into a beaker of water to see how much water it displaces.

Answer 1

To determine which magnet has the most magnetic energy, the best approach would be to measure how close each magnet can get to a metal object before picking it up.

This method provides a practical way to assess the strength of the magnetic field each magnet produces, as the distance at which a magnet can attract a metal object is directly related to its magnetic strength and energy.

The other methods suggested (measuring current, weighing the magnets, or measuring water displacement) do not directly relate to the magnetic energy stored in the magnets.
