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?
a
Attach wires to the ends of each magnet and measure the currents going through the wires.
b
Put each magnet into a beaker of water to see how much water it displaces.
c
Measure how close each magnet can get to a metal object before picking it up.
d
Record the mass of each magnet by measuring it on a balance scale.
c. Measure how close each magnet can get to a metal object before picking it up.
The strength of a magnet depends on its magnetic field. The magnetic field is what allows the magnet to attract or repel other magnets or magnetic materials. By measuring how close each magnet can get to a metal object before picking it up, Kayla can determine which magnet has a stronger magnetic field and therefore more magnetic energy stored.
