His writing covers science, math and home improvement and design, as well as religion and the oriental healing arts. Putting a piece of iron or steel inside the coil makes the magnet strong enough to attract objects. The strength of the magnetic field of an electromagnet increases when: (a) The current is increased (b) The number of turns is increased (c) The turns of wire are pushed closer together so that the length of the solenoid becomes shorter Add more loops of wire to the solenoid. For example, if you double the number of coils, you double the strength of the inductive field. Magnet stacking One way to make weak magnets stronger is by stacking more of them together. Why don't libraries smell like bookstores? The strength of an electromagnet depends on the electrical current which flows through its wires, but not on what drives that current. The strength of magnetic field generated is proportional to the amount of current through the winding. The more induced voltage, the stronger the electromagnet. Magnetic field.
