Answer:
move the wire loops closer
Explanation:
because the closer t they are the more concentrated the energy is in that specific area
Lisa can move the wire loops closer together to increase the strength of the electromagnet. Option C is correct.
What is electromagnet?
An electromagnet is a magnet whose magnetic field is generated by an electric current. Wire coiled into a coil is used to make electromagnets.
A current flowing through the wire produces a magnetic field that is focused in the hole.
The strength of the electromagnet is increased by;
Adding further twists to the coil by wrapping it around a piece of iron and increasing the amount of electricity that flows through the coil.
Hence, option C is correct.
