The magnetic force of electromagnet is related to the number of (1) series batteries. 2, the number of turns of the coil winding).
The magnetic force of electromagnet is related to the number of turns of coil. The number of turns of the coil is large, and the magnetic force is large; The number of turns of the coil is small and the magnetic force is small.
The magnetic force of electromagnet is related to current, coil turns and iron core. The greater the current, the more turns of the coil, and the greater the magnetic force when there is an iron core.
Electromagnet: A device that generates electromagnetism when energized. A conductive winding matching its power is wound around the outside of the iron core. This coil with current is as magnetic as a magnet, also called an electromagnet. We usually make it into a strip or hoof shape to make the iron core easier to magnetize. In addition, in order to demagnetize the electromagnet immediately after power failure, we often use soft iron or silicon steel materials with faster demagnetization speed. Such an electromagnet is magnetic when it is energized and disappears when it is de-energized. Electromagnet is widely used in our daily life, and the power of generator is greatly improved because of its invention.
