Sarah the scrap-hauler loves hauling scrap metal with her electromagnet shown below, but her electromagnet isn't strong enough. What is one thing she could do to make her electromagnet stronger?

Answer 1

Sarah can make her electromagnet stronger by increasing the number of turns in the coil of wire or by increasing the current running through the coil. By doing so, the magnetic field generated by the electromagnet will be stronger, resulting in a stronger force on the scrap metal. She could also use a stronger magnetic core material, such as iron, to amplify the magnetic field.
