Key learning points: - The more turns of wire in the coil of an electromagnet, the stronger its magnetic field. - The greater the current through the coil of an electromagnet, the stronger its magnetic field. - The more closely spaced the coils of wire of an electromagnet, the stronger its magnetic field. - An electromagnet made from bare wire will not work if adjacent turns are touching. - A soft iron core increases the strength of an electromagnet because it becomes magnetised when it is turned on.\n
