"Electricity is all around us."(paragraph 1)

"While electricity is the force responsible for electric currents and fields, magnetism is responsible for magnetic forces and fields."(paragraph 5)

"Many magnets, however, get their strength from a little electric boost."(paragraph 6)

"This electromagnetism enables us to use compasses, whose needles are ussually composed of natural magnets such as lodestone, to detect the Earth's north and south poles, no matter where we happen to be." (paragraph 7)

Answer 1

"Many magnets, however, get their strength from a little electric boost." (paragraph 6)

This directly supports the idea that electricity gives magnets their strength (electromagnetism).
