The laboratory electromagnet manufacturer tells you that electromagnets generate electromagnetism based on electromagnetic induction. Because they are usually made into strips or horseshoes, the iron core will be easier to magnetize when used. In terms of materials, it usually chooses soft iron or silicon steel. which can quickly demagnetize, the frame electromagnet is widely used in life, and its appearance has greatly improved the power of the generator.
1. The size of the current
The magnetism of the electromagnet is realized by energizing it, so the on-off of the current directly affects its normal use. The laboratory electromagnet manufacturer tells you that when the current is turned off, the magnetism of the electromagnet will disappear immediately. Similarly, It works normally when the current is turned on. In addition, the magnitude of the magnetism is also controlled by the current. The greater the current intensity, the greater the magnetism, and vice versa.
2. The number of turns of the coil
The laboratory electromagnet manufacturer tells you that the magnetism has been mentioned above and is related to the current, but in addition, the magnetism of the electromagnet can also be controlled by the number of turns of the coil. More, so the magnetism will also be stronger, also, if the number of turns is small, the magnetism of the electromagnet will be weakened, so the magnetism can be well controlled by the amount of current and the number of turns of the coil.
3. The poles of the electromagnet
In addition, since the electromagnet is magnetic, it must be affected by the magnetic pole. The laboratory electromagnet manufacturer tells you that the magnetic pole of the electromagnet can change the direction of the current and thus affect its use. It is also very practical in actual operation. The control of the electromagnet will be more convenient and thorough.
4. Magnetization of iron rods
In addition, the electromagnet has an iron rod in its coil when it is made. Although the iron rod itself is not magnetic, once it is magnetized, it has the ability to affect the electromagnet. The magnetic field formed by the iron rod itself plus the coil's The magnetic field, so that the total magnetic field will be stronger, thereby greatly improving the magnetism of the electromagnet.
The laboratory electromagnet manufacturer tells you that the above are several key factors that affect the magnetism of the electromagnet. The grasp of these factors can make it better to use it and have a better use effect.
