By applying an electric current through a coil of wire wrapped around an iron shaft, the entire ensemble immediately turns into a deceptively strong magnet, complete with a north and south pole. By increasing the current traveling through these windings, the power of the magnet can be directly manipulated. With sufficient power, electromagnets become stronger than any natural magnet on the planet and can be used commercially from lifting entire cars off the ground to scanning the inside of a patient’s brain in an MRI....

If you want the most professional appearance, print directly on the tabs. Writer Bio
